IntroductionMPHusky has been in the Cable Tray business since 1955. Over the past 50+ years of leadership and service, MPHusky has gone through several transformations and mergers, including Husky/Burndy and Metal Products, thus leading to what is today MPHusky—America’s leading manufacturer of Cable Tray and Cable Bus Power Distribution Systems.

Throughout these changes one thing has remained constant—the “Husky” drive to be the most reliable, highest quality, cost effective and innovative manufacturer of Cable Support Systems and Cable Bus Power Distribution Systems. We have an unsurpassed commitment to customer satisfaction and service, and we are eager to earn your loyalty and trust.

Description and Selection

Cable Tray systems provide rigid structural support for cables in a variety of commercial and industrial applications. The basic styles of cable tray are: Ladder, Trough, Center Rail, Wire Basket and Channel. For a more comprehensive description of the construction and utilization of these types of tray, turn to Sections 2, 3, 4, 5, 6, 7, 8,13, 14 and 15 in this catalog.

Husky LadderLadder consists of two longitudinal side members connected by individual traverse members. It is intended for use as a power cable or control cable support.

Husky TroughTrough has a corrugated solid or ventilated bottom, 4” rung spacing or flat bottom pan design which is contained within longitudinal side members. It is especially appropriate for control and instrumentation cables.

Husky ChannelChannel is a one piece support with either ventilated or solid bottom sections. These sections are used with a single power cable, multiple control, or signal circuit cables.




4

Description and SelectionHusky Wire BasketTechtray is a wire mesh cable tray system that utilizes high mechanical strength steel wire that is welded into a 2” x 2” grid system. This grid system is then formed into channels which support and carry cables.

Husky Pan TrayHusky Way is a one piece formed pan that provides a flat bottom and a fill depth that is almost the same as the outside height of the tray. It is the most economical of all the tray systems.

Since Cable Tray is used in a wide variety of applications and under widely varying conditions, it is im-portant that you gain an understanding of material specifications and structural design and apply that knowledge when selecting trays and specifying fittings, parts, and accessories. Some of the considerations are:

NEMA Class / CSA Class1. Using the charts below, determine the correct class of tray as it relates to your desired loading capacity per foot and support span. You will also need to know the weight of the cable and at what span it will be supported.

Material 2. MPHusky cable tray is available in aluminum, stainless steel and hot dip galvanized after fabrication or pre-galvanized steel, galvannealed and fiberglass.

Tray Depth 3. A loading depth from 3” to 7” is available.

Tray Width 4. Standard widths are 6”, 9”, 12”, 18”, 24”, 30” and 36”.

Tray Type 5. Seven types of tray are available: Ladder, Trough, Channel, I-Beam, Center Spline, Fiberglass, and Wire Mesh. Lad-der is available with either 6”, 9”, 12” or 18” rung spacing. Both Channel and Trough are available with either solid, non-ventilated or ventilated bottoms.

Radius of Fittings 6. All fittings normally come with a 12”, 24” or 36” radius in styles and material to match any tray selection.

NEMA LOAD CLASSIFICATIONThe National Electrical Manufacturers Association (NEMA) has standardized the classification of cable tray based on the load to be carried per foot, and the distance between span supports. The load per foot should include not only the cable, but additional load factors for wind, snow, ice, etc. For more informa-tion on loading, see page 1.12 in this section.

Materials & ConstructionCable tray systems are commonly fabricated from a corrosion-resistant metal or from a metal with a corrosion-resistant finish. The selection of the proper material is essentially an economic consideration.

Every cable tray installation places requirements on the mechanical properties of the material from which it is fabricated. These properties influence the spacing frequency of supporting members, and the ease of installation. The selection of the material may also be dependent upon electrical (conductivity), physical (appearance), or chemical (corrosion resistance) properties, according to the demands of the specific installation. Although there are numerous metals available which could satisfy the basic requirements, certain wrought aluminum alloys and low carbon steels meet these requirements most economically.

Wrought Aluminum AlloysPure aluminum is soft and ductile. However, most com-mercial uses require greater strength than pure alumi-num affords. This strength is achieved by the addition of other elements to produce alloys which singly, or in

combination, impart strength to the metal. These alloys have been classified into seven categories accord-ing to their chemical composition, and have been given numerical designations for each series of alloys of 1000 through 7000 by the Aluminum Assoc. In addition to alloying the pure aluminum, further strengthening is pos-sible by heat treating.

Heat-Treatable Alloys—the initial strength of alloys in this group is enhanced by the addition of such alloying elements as copper, magnesium, zinc and silicon, and are designated as 2000, 6000, and 7000 series. Since these alloys singly, or in various combinations, show increasing solid solubility in aluminum with increasing temperature, it is possible to subject them to thermal treatments which will impart pronounced strengthening.

Non-Heat-Treatable Alloys—the initial strength of alloys in this group depends upon the hardening effect of elements such as manganese, silicon, iron and magnesium, singly or in various combinations.

The non-heat treatable alloys are designated as 1000, 3000, 4000, and 5000 series. As these alloys are work-hardenable, further strengthening is made possible by various degrees of cold working, denoted by the “H” series of tempers. Alloys containing appreciable amounts of magnesium when supplied in strain-hardened tempers are usually given a final elevated temperature “stabilizing” to insure stability of properties.

In determining the proper aluminum alloy for structural applications, such as ventilated cable tray systems, the design engineer should recognize the advantages inherent in using alloys that are heat-treatable and of being able to fabricate the structure from materials possessing known minimum values of yield strength.

Cable tray products are most widely formed from the 6000 series alloys. Alloys in this group contain silicon and magnesium in approximate proportions to form magnesium silicide, thus making them capable of being heat-treated. Major alloys in this series are 6061 and 6063, which are among the most versatile of the heat-treatable alloys. Though not as strong as most 2000 or 7000 alloys, the magnesium-silicon (or magnesium silicide) alloys possess good formability and corrosion resistance.

Basic structural members of aluminum cable tray systems can be made from 6063-T6 aluminum extrusions, a material which economically meets the requirements of the majority of installations. The 6063-T6 alloy has adequate strength and good corrosion resistance. It is light weight, maintenance-free, and because of the non-magnetic properties of aluminum, keeps electrical losses to a minimum.

Materials & ConstructionSteelSteel cable trays are used principally in environments which are relatively free from corrosive attack. They are available with various types of corrosion-resistant finishes; usually hot-dip galvanized. The main advantages of using steel in cable tray fabrication are its high strength and low cost. Its disadvantages are increased structural weight, poor corrosion-resistance, and low electrical conductivity.

The idea that all steels are the same, except for chemical disposition is false. Carbon steels may be produced with chemical compositions (carbon, manganese, phosphorus, sulphur and silicon) within the specified limits of a given grade and still have characteristics that are widely dissimilar. Each grade and quality variation has a useful place, depending upon the end use and the methods of fabrication.

Basic components of steel cable trays are normally fabricated from either hot or cold rolled steel strips of commercial quality. Steels in this category are ASTM A-1011 CS Type B (formerly ASTMA-569) and ASTM A-1008 CS Type B (formerly A-366). Pre-galvanized steel conforms to ASTM A-653.

Stainless SteelToday, hundreds of different alloy combinations exist for the endless variety of applications which utilize stainless and heat resisting steels. The primary elements added to obtain the various properties required in the steels include chromium, nickel, manganese, silicon, molybdenum, and the stabilizing elements of titanium columbium and tantalum.

Stainless steel contains at least 10 percent chromium, along with other elements to develop specific properties. Depending on the quality of the elements present in a stainless alloy, it will have a metallurgical structure which will be characteristic of the basic stainless steel groups. Metallurgists refer to these groups as the martensitic, ferritic, austenitic and precipitation hardening stainless steels. All standard austenitic alloys are given numbers in the “200” and “300” series, while the martensitic and ferritic alloys are numbered in the “400” series.

If your job calls for stainless steel, please contact the MPHusky factory for assistance in determining the correct type for your

specific application.

MPHusky offers cable trays and accessories in both the 304 and 316 series. These austenitic alloys are remarkable in several respects. Unlike the other two classes, they contain nickel in quantities from 4 to 22 percent, while the percentage of carbon is kept relatively low. When chromium is increased for improved corrosion resistance, nickel must also be increased to retain the austenitic structure.

304 stainless steel has chromium and nickel increased and carbon lowered to reduce carbide precipitation and increase corrosion resistance. Lowering the carbon content also makes welding easier.

316 stainless steel has molybdenum added to improve corrosion resistance and high tempera-ture strength. The carbon content is also lowered to improve welding performance.

GalvannealedGalvannealed or Galvanneal, is the result from the com-bined process of galvanizing and annealing the steel. The galvanization is made through the hot-dipping (hot-dip galvanizing) process and gives a very fine grayish matte finish. Galvanneal does not flake off its galvanized coat-ing when formed, stamped, and bent. The very fine matte finish acts like a primer and paint easily adheres to the tray. It is very rust proof, only white to dark grey marks ap-pear if it comes in contact with water. Galvanneal sheets offers good paintability, weldability, corrosion resistance, and formability. It is extensively used in the au-tomotive, signage, electric equipment, and other indus-tries requiring good paintability and long reliable service life.

Corrosion ResistanceThe underlying causes of corrosion are the same for all metals, all stemming from electrochemical phenomena. But the ways in which corrosion manifests itself are characteristic of each particular metal. Steel corrodes in the atmosphere with the formation of rust, which devel-ops very rapidly on unprotected surfaces. In a clean atmosphere, aluminum slowly develops a white or silver grey patina.

Aluminum surfaces weather by a characteristic of pitting, and corrosion rates are often assessed by measuring the depth of the pits. The rate of pitting falls off after the first year or two, moving gradually to a standstill.

The strong, heat-treatable alloys of aluminum, with copper as one of the chief alloy elements, or certain fully heat-treated alloys with magnesium and silicon as major alloying elements, may manifest another type of attack, inter-crystalline in nature, which may cause more pronounced loss of strength if allowed to continue. Such materials may require protection by painting, cladding, or metal spraying, depending on the environ-ment.

Several characteristic modes of corrosive attack may be distinguished as follows:

Simple Chemical Attack—the solution of a metal by an acid is an obvious example of simple chemical attack. Simple chemical attack occurs when sulfides are in contact with steel or copper. Ordinarily, aluminum is not subject to such attack. A classic example of such chemical attack is sludge retaining rainwater in the bottom of guttering. In this case, a corrosive solution is held in constant contact with the metal, and rapid attack may follow.

Electrochemical Corrosion—corrosion of a metal accelerated through contact with another metal in moist or wet conditions is known as bimetallic or electrolytic corrosion. This corrosion is due to the action of a simple voltaic cell. The presence of a conducting solution is essential to this phenomenon but the presence of dissimilar metals is not essential provided that a difference of potential exists.

In addition to the nature of the two metals, the extent of galvanic attack depends upon many other factors. Among these are:

Nature of ions present in the electrolyte •Polarization effects•Effect of stable surface films on the metal•Relative areas of anode and cathode•The physical nature of the corrosion product•Temperature variations•

Each of these factors can influence the total resistance of the circuit. The following table is a compilation of solution potentials of metals and alloys with respect to a calomel electrode. It provides an initial guide to the possible effects of bi-metallic contact.

Corrosion ResistanceThe composition of the base metals has no measur-able effect on the life of zinc coatings. However, the composition of the base metals is the major factor in the years to perforation.

The corrosion rate of zinc varies more with the type of atmosphere (marine, industrial) than does that of steel or iron.

The chloride content of sea air apparently has an accelerating effect on the corrosion of zinc coating.

Rainfall removes about 75% of the corrosion products from zinc surfaces if the results of tests in rural, indus-trial and marine exposures are averaged together. The residual corrosion products remaining on the surface be-come basic in character and exert a retarding influence on corrosion. In highly industrialized or polluted atmo-spheres, this basic film may not exist, a fact which helps explain the more rapid attack experienced in such atmospheres.

Indoor atmospheres correspond in a general way to that prevailing outside in a given locality. Variations in humidity and temperature are somewhat less ex-treme and there is no rainfall indoors to dissolve and remove soluble corrosion products. In general, it may be assumed that the protective life of zinc coatings indoors is at least five times greater than that of coatings of the same thickness exposed to the outdoor atmosphere in the same locality.

The indoor corrosion of zinc may be severe when moisture condensation is frequent and air circulation is restricted. This effect is particularly bad in humid, tropical locations with nightly condensation.

These conclusions indicate zinc coatings will in any event have an acceptable service life expectancy regardless of how the end point of failure is defined. However, it should be noted that whenever maintenance, such as painting, is neglected, it is unreasonable to expect galvanized steel to last indefinitely.

Finishes

MetallicCable trays fabricated of steel can be protected from corrosion by coating with another metal using one of the following methods:

Continuous Hot-Rolled Galvanizing• ASTM Designation Specifications for Zinc Coated Galvanized) Iron or Steel Sheets, Coils, and Cut Lengths—This process applies a zinc coating to sheet steel prior to fabrication of the product (pre-galva-nized cable tray) by passing the metal downward through a molten ammonium chloride flux bath, and then into the zinc and out again by means of rolls. The MPHusky standard zinc coating designation is G90, which has an average zinc coating weight of 1.25 ounces per square foot of steel for an average coating on both surfaces of 1.06 mils.

Hot Dipped Galvanizing After Fabrication• ASTM Designation A123 Specification for Zinc Coat-ing (Hot Dip) on Assembled Steel Products—This process is used to apply a zinc coating to an already fabricated product. The product is first cleaned in a caustic bath, then further cleaned by a pickling acid bath. The article is then thoroughly rinsed and dipped in a bath of molten zinc. The nature and thickness of the coating depend largely on the im-mersion rate, temperature of the bath, immersion period, and withdrawal rate. The resulting coating consists of an outer layer of relatively pure zinc, and lower layers of iron-zinc compounds. Generally, hot dip coatings are highly non-uniform, except on very simple shapes and are usually thick-est at small recesses (unless these remain uncoated altogether). The advantage of this method is that the zinc applied is thicker than when applied by other processes. However, the protective characteristics of zinc coating under atmospheric conditions have been found to be equal, regardless of process: i.e. zinc coatings of the same weight have approximately the same service life.

Galvannealed• Galvannealed or Galvanneal, is the result from the combined process of galvanizing and annealing the steel. The galvanization is made through the hot-dip-ping (hot-dip galvanizing) process and gives a very fine grayish matte finish. Galvanneal does not flake off its galvanized coating when formed, stamped, and bent.




11

The corrosive nature of sea water and of coastal envi-ronments is partly due to the low electrical resistance of salt solution. Similarly, the bad effects of industrial atmospheres on metals arise largely from the sulphur compounds, sulphurous and sulfuric acids, which are largely formed as a result of burning coal, and which dissolve in the moisture in the air or in the rain as it falls, or in films of condensed water on the metal.

To summarize, the extent and type of moisture is an important factor in determining the severity of galvanic attack. For indoor service, where wetting is infrequent, galvanic corrosion normally is no problem. Outdoors, attack may be relatively rapid in sea coast and industrial environments, where contamination, hence conduc-tivity, of rain and condensed moisture is high. Several general rules can be applied in selecting metal combi-nations for use in corrosive environments. These are:

Select metals as close together in the galvanic series as possible. For the anodic protection of steel, metals above steel in the series should be selected, or the steel should be galvanized or otherwise protective-coated. Avoid combinations having a smaller area of the more anodic metal than of the cathodic, to avoid excessive current density on the anodic areas. Insulate dissimilar metals wherever possible to minimize galvanic corrosion.

Aluminum AlloysThe corrosion-resistance of aluminum alloys is due to the presence on the surface of a very thin protective film of aluminum oxide which has strong self-healing properties when damaged. The oxide film begins to form immediately on the surface of the bare metal exposed to air and grows rapidly for several days, then slowly for a month, when it reaches a thickness of approximately 0.0000002”. Corrosion of aluminum can only occur when the oxide film is damaged or removed and conditions prevent its formation.

Substances which may come in contact with aluminum can be divided into three groups:

Those substances which attack the oxide film. These are most strong alkalis, mercurial compounds, and most strong acids.

Substances which cause localized breakdown of the oxide film (pitting) - and for which aluminum is suitable only under certain conditions, such as some natural fresh waters and aqueous solutions containing traces of mercury, copper, or other heavy metals.

Corrosion ResistanceSubstances which do not attack the oxide film. The majority of substances fall in this group, including many industrial chemicals.

The majority of aluminum installations give perfectly satisfactory service, free from corrosion, and only in exceptional cases do problems occur. When problems do occur, they can be attributed to one or more of the following causes:

Wrong choice of alloy•Exposure conditions•A bimetallic joint which causes galvanic corrosion•Crevices•Unwise location of the aluminum assembly, resulting •in deposition corrosionContact with aggressive chemicals•

Among the heat-treatable alloys, the 6000 series has good resistance to industrial and marine atmospheres.

With the exception of certain corrosive chemicals, no corrosion at all will occur if water is not present. Thus, indoor installations that are not in actual contact with water or installations which are maintained in dry conditions, will not corrode.

Steel with Zinc CoatingsThe data from which comparative performance of different types of zinc coating can be inferred, are generally obtained from comprehensive exposure tests in various atmospheres, such as those conducted since 1926 by the American Society of Testing Materials. From the results of these tests, the following conclusions can be made:

The corrosion rate of zinc on galvanized sheets is practically linear in industrial or rural atmospheres, and in a marine atmosphere that is polluted with industrial contaminants. Thus, in these atmospheres, a sheet with double the weight of coating than that of another sheet can be expected to last twice as long before rusting of the base metal occurs.

LoadingThis section presents guidelines for classification of design conditions with respect to weather factors, meth-ods of determination and application of various types of loadings encountered, maximum allowable work-ing stresses and other pertinent considerations. This information will assist the designer in evaluating ma-terials and product catalog information so that he can design a system which will achieve the desired strength and rigidity at the lowest possible installed cost.

Load ClassificationLoads on structures are usually divided into three types:

Dead loads• that do not change their magnitude or their position during the life of the structure.Live loads• that change their magnitude, their position and/or their direction during the life of the structure.Dynamic loads• that are caused by the motion of the live load, or the movement of the structure.

Because of their general nature, these load classifica-tions can be used for any structure. However, for the purpose of establishing a practical load classification for cable tray system design, it is necessary to create additional subdivisions and provide a guide for assumption of specific loads.

Thus, for cable tray system design, the three basic load types are also considered as follows:

Dead LoadsSince dead loads are the weight of the members that make up a tray or tray support, they have a known value. A summation of the weights of the individual members is all that is required to calculate the dead load.

Live LoadsIn cable tray design, dynamic loads are considered to be as follows:

The design load is the weight of cables, cable tray •accessories, and sometimes workers (which vary in both magnitude and position). Cable only design loads can be determined by adding the component weights of the system. Any provision for workers will require an assumption of magnitude and position—for practical purposes, an assigned weight acting at mid span of the tray.

Parasitic loads such as ice, snow, wind, traction, and •electromagnetic forces exist only because the tray exist. They are the most difficult to determine, and different assumptions can be made about their effect on the overall loadings. The following information will provide a general guide.

13

Three general degrees of loading due to weather conditions are recognized in the National Electrical Safety Code, and are designated as heavy, medium and light loading.

Districts in the United States in which these loadings are normally applicable are indicated in Figure 1. Values used in determining conductor loadings under these conditions for ice, wind and temperature are given in the Table 1—Degrees of Loading Due to Weather. How-ever, modifications of these values are necessary when applied to cable tray systems, since the NESC is concerned primarily with the construction of overhead supply and communication lines. These modifications are:

Ice LoadingThe NESC loading of 1/2” thickness is applied to both cables and cable tray. In applying loadings to interlocked armored cables, and bare stranded conductors or suspen-sion cables, the coating of ice is considered as a hollow cylinder with an inside diameter equal to the outside diameter of the cable or strand. Ice is assumed to weigh 57 lbs. per cubic foot.

Snow LoadingThe NESC does not consider snow loading, and in general this also applies to cable tray systems. However, in the case of a solid cover on a tray, the minimum load of 5lbs. per square foot should be used for outdoor installations where snow is a factor.

Wind LoadingThe NESC loadings are modified as follows, in order to provide adequate protection against the maximum wind velocities encountered with consideration of the shapes of the various structures (not considered by NESC).

Wind velocity—in the loading tables, wind means horizontal wind. Wind velocity should be considered to be true wind speed, corrected for instrumentation errors. Any variation of velocity with height is not considered. All structures will be under 100 feet in height, and 100% of the ground velocity is assumed to be adequate.

Wind loads—the exteriors of all structures, with the exception of cylindrical structures, should be loaded with a wind pressure normal to the surface, having an inten-sity given by the formula:

LoadingWp = C VpWp = wind pressure in pounds per square footC= coefficient depending upon the size, shape, and position of the structure in the wind and having values specified in Table 2, Shape FactorsVp = impact pressure = 0.00256V² where V= the design velocity. Values of Vp may be obtained from Table 3, Impact Pressures

Wind direction and distribution—the allowance for wind pressure shall be made assuming the wind from any possible direction to be critical. Wind loads shall be considered uniformly distributed. Average annual tornado frequency, average wind velocities for different areas of the U.S. are shown in Figs. 2 and 3.

Traction ForcesTraction forces are caused by the cables starting and stop-ping during the cable installation period and they vary in magnitude and direction. They are of such nature, there-fore, that no general assumptions can be made to provide for them. However, the safety factors selected for the basic design stresses should be conservative enough to provide for these forces when they do occur.

Electromagnetic Forces

These forces, caused by short-circuit current during a ca-ble fault, vary in magnitude and position. It is impractical to make an assumption providing for them. Ordinarily, the safety factors selected for the basic design stresses will be adequate. However, in installations where these forces are of such magnitude that they become a factor in the design of the cable tray system, adequate provision must be made so that the design stresses are not exceeded.

(The Average Annual Number of Days with Thunderstorms for various areas of the United States are shown in Figure 4).

Dynamic Loads

Impact loads which result because the live load is in motion, are loads in addition to the static weight of the live load. Such loads could be caused by cables being dropped onto it, or by workmen walking on it or climbing up or down a ladder leaning against it. These loads are provided for in the same manner as traction forces—the safety factors selected for the basic design stresses should be conservative enough to provide for these forces if they occur.

15

Inertia loadsInertia loads are caused when the structure itself is in motion, such as may occur during an earthquake. It is usually considered that an earthquake gives the structure a horizontal acceleration, and the resulting acceleration an deceleration cause forces proportional to the mass and to the acceleration and deceleration. These loads represent special design requirements, and the design loading should be in accordance with the ASA’s “American Standard Building Code Requirements for Minimum Design Loads in Buildings and Other Structures” or other suitable specifications. Seismic probability for various areas in the United States is given in Figure 5.

Design LoadingsBasic cable trays are designed on the basis of maximum allowable stress for a certain section and material. There-fore, the allowable cable load will vary with span, type and width of tray. The design loadings for cable tray are given in the form of load tables. These tables appear in another section of the catalog.

The design loadings are to be used for designing standard supports, which necessitates assuming design loadings for the cable trays to be supported. If the design loadings of the cable trays exceed those listed, or if the assumptions for the loading of the open area or frame type supports exceed the conditions herein, standard supports cannot be used. Special supports must be designed on the basis of data for actual conditions.

LoadingApplication of LoadsThe application of all loads shall be to “conventional” or “simple” framing (unrestrained, free-ended), which as-sumes that the ends of the members are connected for shear only and are free to rotate under load.

When calculating lateral strength, the lateral and vertical design loads shall be taken as acting simultane-ously. It is assumed that maximum ice loads and maxi-mum wind loads do not occur simultaneously.

When calculating longitudinal strength, the longitudi-nal design loads shall be taken without consideration of the vertical and lateral design.

When latticed structures are concerned, the actual ex-posed area of one lateral face shall be used in computing lateral and longitudinal loading.

Where a change of direction or suspension cables oc-curs, the loading upon the structure, including workmen, shall be assumed to be a resultant load equal to the vec-tor sum of the lateral wind load and the resultant load imposed by the suspension cables due to their change in direction. In order to obtain these loadings, a wind direction shall be assumed which will give the maximum resultant load.

16

It is recognized that deformation, defection, or displace-ment of parts of the structure, will in some cases change the effects of the loads assumed. In the calculations of stresses, however, no allowance shall be made for such deformation, deflection, or displacement of supporting structures.

Members subject to stresses produced by a combination of wind and other loads may be proportioned for unit stresses 33.3% greater than those specified for dead and live load stresses provided the section thus required is not less than that required for the combination of dead load, live load, and impact (if any). A corresponding increase may be applied to the allowable unit stresses in their con-necting rivets, bolts, or welds.

Members subject to stresses produced by the assumed Class 1 tray lateral loading may be proportioned as specified for wind loads.

LoadingDetermination of Design LoadingsThe following procedures and values for design loadings have been established by MPHusky. The data is based on test results under various installation conditions, and the experience of practical application in the design of com-ponents and systems.

In each instance, the loadings are given for three classes of design conditions as shown in Table 4, Design Conditions.

These classifications have been established from modifi-cations of the National Electrical Safety Code’s “Degrees of Loading Due to Weather Conditions”.

The concept of “Cables in Free Air” for power distribu-tion and control cables has been adopted primarily for economic reasons. Cable tray support systems should be designed, whenever possible, for minimum installed cost. In order to achieve this objective, the engineer must bear in mind that the general design rules established for aluminum and steel structures are not always compatible with design rules for a cable tray system. This is particu-larly applicable in the case of restrictions on deflection.

Since the most economical cable tray system uses heat treated aluminum alloys, or high strength steels with long spans, any limitation on deflection which will not permit the best utilization of material and design will increase the cost. By limiting the maximum fiber and shear stress used in the design the adequacy and safety of the struc-ture is assured.

Why Limit Deflection?The primary reason to limit deflection in cable tray systems is appearance. Engineers and owners take pride in the appearance of their installations. So rigid restrictions on deflection of cable trays installed at eye level or in a prominent location are common. However, it is neither economical nor good engineering practice to restrict deflection of a cable tray system in less prominent areas.

Methods of Decreasing DeflectionThere are various ways to limit deflection of a cable tray. If the objective is minimal installed cost, they should be considered in this order:

Decreasing stress by decreasing the bending •moment. This can be accomplished by introduc-ing restraining moments at the end of a span in the form of a rigid support. The deflection in a continu-ous beam, with negative bending moments at the intermediate support points, is only a fraction of the deflection in a simple beam.

Increasing depth of the tray. • Deflection in any loca-tion can be reduced by increasing the depth of the load-carrying side members and/or by adding to their cross-sectional area. Adding to the depth generally utilizes the material most economically.

Increasing modulus of elasticity. • Since the mod-ulus of elasticity of steel is 29 x 106 psi, and that of aluminum alloys is only 10 x 106 psi, greater defor-mation of aluminum alloy trays is to be expected at any given stress level. Under its own weight, an aluminum beam will defect the same amount as an identical steel beam, since not only the weight, but also the modulus of elasticity is only one-third that of steel. However, under the same applied load (disregarding the beam’s own weight), aluminum will deflect almost three times as much as steel.

Loading(cont’d) Therefore, consideration must be given to the •choice of material for any one location, for an isolated run or for an entire installation.

Decreasing span length. • For economic reasons, this method of reducing deflection should be a last resort, since it increases field labor considerably. However, it can be an effective means to improve the appear-ance of an installation when the number of spans to be reduced is small in comparison to the number in the entire installation.

Deflection Criteria Applied to Cable TrayDesign rules and specifications developed for steel should not be applied to aluminum alloys since this would not permit the most economical use of these materials. De-flection criteria which apply only to steel, and should not be used when the most economical system is desired in-clude:

Span-deflection ratio• - Example: Deflection is limited to 1/300 of the span by the National Electrical Manufacturers Association specifications for structures supporting air switches. While very important in that instance, as even slight deflec-tion could cause misalignment in the operating mechanism and result in binding and difficult switch operation, the application of this specification to a cable tray is uneconomical and not recommended.

Depth to span ratio• - Example: The American Institute of Steel Construction, in the specifications for buildings, specifies the depths of beams and girders in floors to be not less that 1/24 of the span, or not less than 1/20 of the span where shock or vibration may be encountered. This specifica-tion ensures a certain rigidity and levelness of the structure which is important in that in-stance, but cannot be justified for cable tray systems because of the higher cost involved.

Deflection constant• - Example: Deflection is limited to a certain amount by an engineering company for a tray system. While such specifications might make a system using 8-foot spans look better, it prohibits the use of more economical designs with longer spans which have a much greater deflection and still look acceptable. Such a specification increases the cost of the tray system unnecessarily, especially if the trays are to be installed well above eye level.

SummaryAs a guide, a span-deflection ratio of around 1/200 satisfies most owners. This ratio provides an allowable deflection of 0.6” in a 10-foot span, 0.72” in a 12-foot span, and 1.20” in a 20-foot span under the actual loads encountered. Data for calculating deflection is presented in Table 5, Constants for Beam Deflections.

*Maximum Deflection for Continuous Beams up to and including 5 spans.

__________

Example: A cable tray with specified load has a simple beam deflection of 1.92 inches at mid-span. Find the deflection for the fifth span of the 5-span installation. From the table above, the maximum constant in the free beam columns is 11.31. Note that this is the center of the span. For the 5-span installation, the maximum constant in the 5-span column is 5.65, which is not in the center, but 7/12 of the span length from the support between spans 4 and 5. The maximum deflection of this fifth span is given by:

A cable tray system must provide protection to life and property against faults caused by electrical disturbances, lightning, failures which are a part of the system, and the failure of equipment that is connected to the system. For this reason, all metal enclosures of the system, as well as non-current carrying or neutral conductors, should be tied together and reduced to a common earth potential.

This includes the structural steel of a building, all piping for water, gas, steam, and sewers, tanks, well casings, down spouts, gutters, siding and roofing. There are two distinct divisions to the grounding problem: System grounding and Equipment grounding.

Electrical Design & GroundingThe following explanation gives the reasons for grounding, and how to provide for it.

System GroundingThe purpose of system grounding is to drain off any excessively high voltages that may accidentally come on the tray system. If the system is properly grounded by means of a low-resistance conductor of sufficient capacity, the current will be carried off to earth immediately with a minimum danger of fire or shock. In a grounded system, an accidental grounding of one of the current carrying conductors will result in a short circuit, and cause a fuse or circuit breaker to open.

Equipment GroundingEquipment grounding means the connection to earth of all exposed, non-current carrying metallic parts of the components of the distribution system. The purpose of this ground is to prevent a voltage higher than earth potential on cable tray or equipment. Grounding thus reduces the danger of shock or fire in the event a live conductor comes in contact with these conductive parts.

Methods of GroundingEffective grounding must be permanent and continuous, and have ample capacity to safety conduct any current likely to be imposed on it. It should also have impedance sufficiently low to limit the potential above ground and to facilitate operation of over-current devices in the circuit. A continuous, underground metallic water supply system is acknowledged to be the best electrical ground. Other suitable methods of grounding include continuous metallic steam and gas piping systems, the grounded metal framing of the building, or an artificial electrode such as a driven steel pipe, galvanized or otherwise protected from corrosion, or a buried metallic plate.

The tray system and equipment ground connections should be made to the same electrode at the service entrance, on the supply side of the equipment used for disconnecting the service. Equipment should be solidly tied in with the system ground. It is also important, that wherever multiple grounds are used, they be tied together in order to avoid any difference of potential between the various parts of the tray system.

Complete rules for grounding are contained in Article 250 of the National Electric Code.

Electrical Properties of Cable TrayMPHusky has always recognized the importance of electrical design, as well as structural design, to provide positive, safe protection to personnel, facility and equipment. Thorough testing has proven that the cable support system must be electrically designed for maximum carrying capacity, in that: power cables may have short circuit capacity from 5000 to 150,000 amperes, and the division of fault current places considerable burden on the support system, even though adequate grounding has been provided. Table 6 shows the division of fault current determined by tests of an aluminum and a steel interlocked armored 3-conductor 4/0 cable on a MPHusky aluminum cable ladder.

It is not the purpose or intent that the support system be used for a continuous ground, but to provide extremely high one second current carrying capacity as a safety feature. The entire system should be grounded at periodic intervals to keep the potential at or below 100 volts in case of a cable fault. MPHusky cable trays are classified by Underwriters Laboratories® as to their suitability as an equipment grounding conductor only.

For ladder or ventilated trough trays, the diam-eter of all cables No. 4/0 and larger must be added together and the total must not exceed the width of the cable tray. Cables must be placed side by side. Table 392.9, Column 1 is used for cables less than 4/0. These cables do not have to be placed side by side. Table 392.9, Column 2 is used for a combination of cables rat-ed larger than 4/0 and smaller than 4/0.

The total cross-sectional areas of the cables in trays with an inside depth of 6” or less, containing control and/or signal cables must not exceed 50% of the cross-section-al area of the tray.

For solid bottom trays, the diameter of all cables No. 4/0 and larger must not exceed 90% of the cable tray width. Table 392.9, Column 3 is used for cables smaller than 4/0. Table 392.9, Column 4 is used for a combination of cables rated 4/0 or larger, or less than 4/0.

For trays with an inside depth of 6 inches or less, containing control and/or signal cables, the to-tal cross-sectional areas of the cables must not exceed 40% of the cross-sectional area of the tray.

For ventilated channel type trays, the total cross-sec-tional areas of all cables must not exceed 2.5 square inches for 3 inch wide trays or 3.8 square inches for 6 inch wide trays.

Sizing Trays for Single Conductor Cables

For ladder or ventilated trough trays, the total diameter of all cables 1000MCM and larger must not exceed the width of the cable tray. Table 392.10, Column 1 is used for cables smaller than 1000MCM. Tables 392.10, Column 2 is used for a combination of cables rated 1000MCM and larger, and smaller than 1000MCM.

Convert a Concentrated Load to Pounds per Linear Foot:

Formula: Concentrated Load times 2 divided by the support span.Example: A 200 pound concentrated load on a 20 foot span would be a load of 20 additional pounds per linear foot. This load can be added to the uniform cable load for a total load and compared to a load shown in a load deflection table.

Convert a Load with a 1.5 Safety Factor to a Load with a 2.0 Safety Factor:

Formula: Multiply the load shown with a 1.5 safety factor by 0.75 to convert the load to a 2.0 safety factor.Example: A load of 100 pounds per foot with a 1.5 safety factor would be 75 pounds per foot with a 2.0 safety factor. The multiplier for a 2.5 safety factor would be 0.60.

Obtain a Deflection for a Load that is smaller than a Load Shown in a Load Deflection Table:

Formula: Divide the desired load by the load shown in the load deflection table and multiply the answer times the deflection shown for the known load in the load deflection table.Example: If the load table shows 200 pounds per foot on a 12 foot span with 1.5 inches of deflection and you want to know the deflection for a 150 pounds per foot on the 12 foot span you would divide the load desired (150) by the load known (200) and multiply the answer (0.75) times the known deflection (1.5”). The answer would be 1.125” deflection at 150 pounds per foot on a 12 foot span.

Calculate a Load for a Shorter Span that is not shown in a Load Deflection Table:

Formula: Take the load of a known span times the span length squared and divide by the span desired squared.Example: The load table shows 100 pounds per foot on a 12 foot span with a deflection of 1.5 inches. To find the load for a 10 foot span that is not in the table you take the load known (100) pounds times the span (12) foot squared then divide the answer (14,400) by the span desired (10) foot squared. The result is 144 pounds per foot on a 10 foot span. Do not calculate longer spans with this formula.

Part 2 Calculate the deflection for the new load of 144 pounds per foot on a 10 foot span:

Formula: Divide the new desired load for the 10 foot span by the known load for the 12 foot span and multiply the answer times the deflection for the known load on the 12 foot span.Example: Take the load on the known span (100) pounds and divide by the new desired load (144) pounds. Take the result (0.6944) times the known span deflection (1.5) inches to get 1.0416 inches. The 144 pound load on a 10 foot span would have a deflection of 1.0416 inches.

The solid bottom design provides total support for cables adding protection. Husky Way can be totally enclosed by adding covers (sold separately) to protect cables from damage, aid in shielding or just for a clean appearance. Husky Way is available in widths from 6 wide through 36 wide.

Aluminum—light weight, maintenance free and non-magnetic. Electrical losses are kept to a minimum with this material, but it does not provide shielding for cables from magnetic fields.

Mill-Galvanized Steel—economical, offering good corrosion resistance, and providing shielding from magnetic fields in an enclosed solid bottom system with cover.

Galvannealed Steel—offers the features shown above, plus it is well suited to painting. galvannealed trays can be painted to match the building color scheme so that it blends in with its surroundings. This system also provides electromagnetic shielding.

Stainless Steel—this material is ideal for corrosive areas, however, because of its non-magnetic feature, it will not provide shielding for sensitive instrument and control or data cables.

We offer a complete line of fittings, covers, accessories, and support items for the Husky Way System to aid in installation and routing.

Husky EMI Enclosed TrayEMI - Electromagnetic Interference ProtectionWith the widespread use of computerized processing equipment in industrial facilities, the minimization of interference induced in the communication link between the in-plant transducers or primary elements and controllers is critical. Depending upon the installation, this link, in most cases a pair of electrical conductors, may be very short, or run for several hundred feet. The longer the control signal able, the more susceptible it is to induced electrical noise. Shielding these cables with a copper braid or metallic tape will protect them from each other, but for long runs a better method of shielding is necessary for protection against exter-nal interferences. To shield these cables individually is impractical because of the large number used in a complex industrial control system. Numerous control signal cables can be protected from interference by using a properly designed and shielded enclosure.

Undesirable voltage can be induced into the control signal cables by five methods: 1. Electrostatic Fields 2. Electromagnetic Fields 3. Plane Wave Radiation 4. Cross Talk 5. Common Mode

Cross talk and common mode interference are functions of the control circuits themselves and must be handled through the proper selection of cable and grounding methods. Plane wave radiation, which is of concern at very high frequencies (30MHz), is generally not a problem in the typical industrial or utility environments.

Electrostatic and Electromagnetic fields are important and directly influence the selection of shield cable enclosures.

Electrostatic interference is caused by stray capacitance between the control signal cable and other conductors and machinery in the area. This stray capacitance can be reduced by completely enclosing the control signal cable in a shielded enclosure which is a good electrical conductor. The measure of electrical effectiveness in this situation is the electrostatic attenuation. This attenuation is determined by measuring the undesirable induced voltage in the control signal cable within the shielded cable enclosure. The enclosure must be properly grounded if it is to act as an electrostatic field.

EMI - Electromagnetic Interference ProtectionElectromagnetic interference is caused by the mutual inductance between the control signal cables and other surrounding power cables and machinery. This mutual inductance can be reduced (shielding the control cable) if the control signal cable is completely enclosed in a good magnetic material. An elec-tromagnetic attenuation parameter can be defined in the same manner as the electrostatic attenuation. unfortunately, good electrical conductors are not effective magnetic (high permeability) materials. The converse is also true. In most industrial installations, shielding must be provided against both electrostatic and electromagnetic fields. Thus a compromise must be made.

The attenuation parameters (electrostatic and electromagnetic) may be measured under laboratory conditions. A test setup is used to create the proper type of field, and the induced voltage “e1” in a control signal cable is measured with the cable suspended in free air. Then the test is repeated with the control signal cable enclosed in the shielded enclosure and the induced voltage “e1” is measured. The shielding effectiveness is given by the ratio of these voltages.

S =

The greater the ratio, the better the shield. Due to the wide dynamic range of “S” for different types of shields, the attenuation is usually expressed as twenty times the logarithm to the base ten of “S”.

A = 20 Log10S or A = 20 Log10 to

The attenuation parameters are both functions of frequency and therefore are usually shown by a graphi-cal display of “As”. (Electrostatic Attenuation) and “Am” (Electromagnetic Attenuation) plotted versus frequency.

Protection of Process Control and Instrumentation CableThe type of signal transmitted by the primary element to the controller determines how sensitive the signal is to extraneous electrical interference. For example, the lower the voltage the higher the impedance and the more susceptible the circuit is to interference.

Since most process type primary elements operate at low voltages and amperes, care must be taken when electing shielding requirements. Typical levels of operation range between less than 100MV to 5V on voltage type elements and 1MA to 50MA on current systems.

Many companies who utilize automated process control find that high additional costs are incurred in eliminating interference in systems, not in the installation, but rather in the check-out and start-up stages of construction.

Protection of Process Control and Instrumentation CableMost of the additional cost can be eliminated in the engineering stages by proper selection of cable and EMI enclosures. The following guidelines will ensure the most acceptable method of installing instrumen-tation:

A. Use twisted parallel pairs - shielded and grounded. B. Separate control wires by frequency and voltage level. C. Route control circuits to avoid power cables and machinery. D. Install control cable in a Husky EMI enclosure. E. Ground the shielded EMI enclosure.

Husky EMI enclosures offer excellent attenuation characteristics while providing a low cost economical installation that allows for additional control cables, check-out and re-wiring. (See Figures 1 and 2 on the following page)

High Voltage Station Switchyard Control Cable ProtectionFor switchyards with primary system voltages of 230kV and above, control and instrumentation cables must be protected from induced voltages that can cause control cable insulation breakdown and damage to control components. This problem becomes more acute when solid state devices, which are even more susceptible to damage by over-voltage, are used on new installations.

The interfering induced voltages are caused by surge voltages which are either continuous wave or im-pulse wave types. The over voltages are present due to periodic transients, switching surges, circuit break-er or GAP flashover. Typically, induced voltages on the control cables can be in the order of 10-15kV if not adequately shielded. A shielded control cable enclosed in an EMI enclosure offers the best overall protec-tion and provides economies in cable installation. EMI enclosures facilitate the placement of control cables above ground where rewiring or additions can be added without the high costs and corrosion problems associated with underground methods.

Tests conducted at a special high voltage test facility demonstrated that Husky’s EMI enclosures offer excep-tional protection by attenuating the high surge voltages to acceptable levels.

Installation InstructionsHusky EMI enclosures can be installed using the same conventional practices and supports associated with standard cable tray.

1. After the support material is in place, clamp the EMI enclosure to the support structure. 2. When joining sections of EMI enclosures use the lower half of the two piece wrap-around splice to connect the sections (1) and (2). 3. After all cables have been installed in the EMI enclosures (3), fasten covers in place (4), making sure that the upper half (or cover) for the warp-around splice is placed over and secured to the butting enclosure covers (5). 4. EMI enclosure covers should be fastened down on two foot centers to maintain the Husky recommended attenuation (6). By decreasing the cover hold-down centers to one foot, an increase in attenuation of 2db would be realized across the frequency spectrum.

Offset Splice Plates for Concentric and Eccentric Reductions

Reducing splice plates are used instead of reducer fittings and offer better versatility and econ-omy since they are less expen-sive and do not require covers.

For concentric reductions, two plates of equal offset are used. For eccentric reductions, one plate is used along with a stan-dard splice connector.

Expansion Joint Splice PlatesExpansion splice plates for Ladder or Trough are designed to allow 1-1/2” free movement between adjacent straight lengths. When using expansion splices, it is important that the straight run be fixed permanently to its support at the ap-proximate center between expansion joints whenever possible, and that all other points be supported in a manner that the longitudinal expansion is not restricted. Supports should be provided within one foot on each side of an expansion joint to ensure its proper functioning. (Hardware included)

Hinged Splices Horizontal and vertical hinged splices offer field flexibility to go around pipes, ducts, and other obstacles that occur during installation. Electrical continuity is main-tained by using bonding jumpers such as AFS-C, which are purchased separately. Hinged splices for Ladder or Trough come in sets of two. Hinged splices for 4” and 6” Channel come as single units. Horizontal hinged splices require field drilling of the long hinge member and all hinged splices require additional supports, as they are not considered to be full strength mechanical splices.

Oxidation InhibitorAn oxidation inhibitor is used where permanent electrical continuity is important. For best results, clean connecting surfaces from dirt and oil by wiping clean and removing oxide coating by abrasion once over with emery cloth. Apply a thin coat of oxide inhibitor on the cleaned surfaces and make connection immediately. Each container of compound is sufficient to effect approximately eighty splices.

Grounding ConnectorsType GC Connectors hold a single through cable and a tap cable while separat-ing the ground conductor from the cable tray surface. Note that the bolt head is mounted on the inside wall of the cable tray to avoid damage to the cable in-sulation. Grounding connectors may be used with aluminum or galvanized steel cable trays and aluminum or copper conductors. When mounted horizontally, the bolt may be used to replace one of the bolts in a splice plate, eliminating the need to drill the tray. When used on aluminum conductors the cable must be scratch brushed and Oxidation Inhibitor must be used on the cable and con-nector. Clamps are tin plated.

Vertical Run Supports

There is a wide variation of vertical run supports possible, depending on the load, support spacing and distance of the run from the wall or supporting structure. It is recommended that support spacing for vertical runs be no less than six feet and no more than twelve feet. Brackets are available for spacing of 3, 12, 24 and 36 inches from the wall to accommodate the various radii bends that may be entering or leaving the supporting wall.

Vertical runs usually consist of either a Z-Bracket for a 3 inch distance from the wall only, or a pair of brackets with the necessary support angles and clips to fasten the tray to the support. Here are two typical installations:

In addition to wall brackets, the proper support angle and number of bracket angle clips for the tray to be used must be determined. For each application, the actual load per bracket must be checked against the maximum allowable load on the bracket.

Bracket AnglesZ-BracketsBracket angles connect two wall brackets, which then serve as a support for vertical runs. Cable trays are then bolted to bracket angles with support angle clips. Bracket angles have a series of slots to allow the attachment of various types of tray of the same width to the same brack-et angle. Fabricated from hot dip galvanized steel.

Z-Brackets support vertical runs at a distance of 3 inches from the wall. They have a slot pattern similar to that of bracket angles and are made from standard 7 gauge Z-shaped HDGAF steel.

Note: A & B dimension locations shown on bracket angle.

Wall Brackets

MPHusky offers a variety of wall brackets to support trays and channels from any wall or vertical support. The design of the brackets takes into consideration whether the trays or channels will be supported singly or two in parallel, on hori-zontal or vertical runs, the distance from the wall, bend radii, etc.

The allowable load of each type of bracket is given below: Condition 1—Where the load is applied at two points (ladders or troughs apart in width). Condition 2—Where the load is applied as a single concentrated load at the end of the bracket (as when supporting vertical runs).

A minimum safety factor of 2 against yield has been used in determining the maximum allowable load. All calculations have been confirmed by testing. Brackets are most commonly used for single or double horizontal runs.

Channel Brackets

Channel brackets will accommodate single or double channel runs with pre-drilled holes for HB-10 Hold Down Bolts or SGB-GU expansion guides, purchased sepa-rately.

Maximum allowable load:Twice the allowable load for the respective channel at a support spacing of 10 feet.

Wall Brackets

Medium Weight BracketsMedium weight brackets are used primarily to support 2 ladders side by side or 2 ladders one over the other. They are made of 3/16” structural angle, welded and hot dip galvanized. The horizontal support angle is continuously slotted to increase the versatility of the bracket.

Maximum allowable load:Condition 1: 1200 lbs.Condition 2: 600 lbs.

Heavy Weight Brackets

Heavy weight, channel type brackets are used to support long spans or multiple ladder or trough installations that exceed the load capacity of ordinary brackets. They are welded from 3” structural steel channel with 1-1/2” channel stiffening members and hot dip galvanized. To develop the full strength of the brackets, the 3, 1/2” diameter bolts for which the wall members are drilled must be used.

Maximum allowable load:4,000 lbs. when applied as 2 equally concentrated loads, spaced at least 2’-4” apart on brackets five feet wide and under; or at least 4’-6” apart on brackets over five feet wide. The capacity is greater when used for a uniformly distributed load.

One Piece Wall Bracket

One piece, light duty brackets are made from 1/8” thick hot dip galvanized steel. Placing one bracket below another allows a minimum vertical spacing of cable trays of 8”.

Maximum allowable load:Condition 1—600 lbs.Condition 2—300 lbs.

Cutting the Wire BasketBelow is a chart detailing how to cut horizontal fittings on Husky Techtray. The green columns are rows that should be removed (cut) and the orange columns are rows that should be left in place (skipped). If the column says to skip one or more, the more rows you skip, the longer the radius will be. There are examples of how to cut tray on Page 13 for your reference. For further details, please consult the factory.

Examples of Cutting the TrayWhen making these radiused horizontal fittings, the outside of the tray will not be cut. Only cut the bottom and the inside side of the tray. To remove a 2” row, cut the longitudinal wires between two transverse wires, on the bottom and inside of the bend. When removing more than one 2” row a transverse wire will be removed for each additional row being removed. Once the proper number of rows have been removed, the inside wires are pulled together and joined using a splice clip.

For non-radiused horizontal bends, simply cut one side out of the adjoining trays and lay one tray on top of the other so they can be connected using the horizontal flex splice kit (Part #SFS-HWB2). The wires need to be removed from the corner of the perpendicular piece.

Horizontal Tees and Crosses—When making tees or crosses, the perpendicular bottom may be up against the straight through member. In this case, one side block is removed from all intersecting corners, so that the tee con-nector can form a radiused corner. If the perpendicular member is overlapped, one square on the bottom, then two sections need to be removed from the corners of the perpendicular piece.

Vertical Bends—Vertical bends are made by cutting the upper side wires and bending the basket up or down.

12H90The above example shows the cutting patternthat would be used to create a 90 degree bend on 12’ wide tray. To make a tighter radius, onlyleave one row in between the sections that arecut. (See chart on page 11)

12H60The above example shows the cutting pattern that would be used to create a 60 degree bend on 12’ wide tray. To make a tighter radius, only leave one row in between the sections that are cut. (See chart on page 11)

12H45The above example shows the cutting pattern that would be used to create a 45 degree bend on 12’ wide tray. To make a tighter radius, only leave one row in between the sections that are cut. (See chart on page 11)

12H30The above example shows the cutting pattern that would be used to create a 30 degree bend on 12’ wide tray. To make a tighter radius, only leave one row in between the sections that are cut. (See chart on page11)

Technical InformationHUSKY CENTRAY—CENTER HUNG AND WALL MOUNT CABLE TRAYS

Material: The spine and the rungs are manufactured from 6063-T6 high strength aluminum. The spine is 3” high and 1-1/2” wide. The rungs is 1/2” wide and 1/2” high.

Construction: The spine is punched on top or bottom to accept the insertion of rungs. The rungs are inserted through the spine and fastened by a four point high pressure staking operation that secures the rung in two locations on each side of the spine. The staking operation holds the rungs in place preventing loose rungs. The ends of the rungs are then bent upward to the desired fill depth (3”, 4” or 6”), measured from the cable support surface to the top of the rung. The rung tips are rounded to prevent sharp edges.

Accessories: Each tray is supplied with a splice/hanger connector that is used to fasten the tray sec-tions together and can also be used to hang the tray from 1/2” diameter hanger rods. The splice/hanger connectors are rectangular in shape and fit inside the tray spine and are secured with 3/8” bolts and nuts that pass through the sides. We offer a complete line of accessories and connectors to aid in installation. Wall mount trays also include three 3/4” wall spacers to space the tray off the wall and aid installation on uneven surfaces.

Lengths: The trays are supplied in 10’ or 12’ lengths that allow 10’ or 12’ support spacing, when hanging tray with the supplied splice/hanger connector.

Widths: All widths are measured to the inside of the rungs, except for bottom rung mount 6”, 9”,and 12” wide trays. These widths include an additional 1-1/2” for the spine width.(Example: a 6” wide bottom mount width is 7-1/2”)

Reduced cable installation headaches, as the cable tray is easily accessed from the ♦side. Cable loading, inspection and retrofit is simplified.

For lightweight reliability, Husky Centray systems are made from corrosion-resistant, ♦high-strength aluminum.

EZ-Clip speeds installation time and minimizes hardware. ♦

Over 50% less support hardware than standard cable trays. ♦

Standard cable tray fittings are no longer needed for elbows, tees and crosses. ♦

For safety and reliability, rungs are firmly attached by the four-point staking method. ♦

All rungs have smooth, chamfered ends. ♦

Top and bottom rung center-supported cable tray and wall rack are CSA certified. (LR 107538)

Top rung Husky Centray meets NEMA Load Class 12C and bottom rung Husky Centray meets NEMA Load Class 12B, in accordance with NEMA Standard VE-1.

Husky Centray systems are classified by Underwriters Laboratories as a grounding means.

Safe, Secure Rung AttachmentHusky Centray rungs come attached transversely through either the top or bottom of the center tubu-lar rail. Each rung is securely staked to the center rail in four places. This provides additional strength and rigidity for reliable cable support. The chances for damaging and loosening rungs during transporta-tion and cable installation are significantly reduced with this safe, reliable and secure method of rung attachment.

Husky Centray rung tips are chamfered to provide a smooth end and limit possible damage to cables or personnel.

INTRODUCTION

For an integrated wire management system, Husky Centray simplifies the support and routing of power and telecom / teledata cabling. A single hanger rod is used at each sup-port point. This makes installation easier by reducing support requirements and elimi-nating the need to pull cable through the trapeze supports. With Husky Centray, cables can be laid in on both sides.

Easy Support and Coupling

Both the support and connection of Husky Centray sections is accomplished by a single splice coupling designed to save time. If additional support is needed beyond the 12 foot or 3 meter intervals, simply use the intermediate support hanger.

Note: Splice coupling and spine attachment hardware are included with each straight section.Step 1

Insert 1/2” rod into coupling

Step 2Attach center section to coupling

Step 3Slide together and tighten

Save time and money:No elbow fittings required.50% less labor.75% less components and hardware than traditional systems.All rungs come firmly pre-attached.

For more than 30 years, MPHusky’s Fiberglass Cable Tray systems have been tested and proven in the harsh environment of the offshore oil and gas industry. Our tray has stood up to the test of being exposed to the corrosive conditions inherent in petroleum products, plus the daily punishment of exposure to wind, weather and salt water. MPHusky Fiberglass Cable Tray gives you the load capacity of steel, plus the inher-ent characteristics afforded by our Pultrusion Technology: non-conductive, non-magnetic and corrosion-resistant. Although light in weight, the strength to weight ratio surpasses that of equivalent steel products. Husky Fiberglass Cable Tray will not rust, nor does it ever require painting. It is available in both polyester and vinylester resin systems, manufactured to meet ASTM e-84, Class 1 Flame rating and self-extinguishing requirements of ASTM D-635. Husky’s Fiberglass Cable Tray comes in gray or blue (polyester resin) and beige (vinylester resin) but is available in custom colors upon request.

Cable Tray Thermal Contraction and ExpansionIt is important that thermal contraction and expansion be considered when installing cable tray systems. The length of the straight cable tray runs and the temperature differential govern the number of expan-sion splice plates required (see Table 1). The cable tray should be anchored at the support nearest to its midpoint between the expansion splice plates and secured by expansion guides at all other support loca-tions (See Figure 1). The cable tray should be permitted longitudinal movement in both directions from that fixed point.

Plot the highest expected tray temperature 1. on the maximum temperature linePlot the lowest expected tray temperature 2. on the minimum temperatureDraw a line between the maximum and mini-3. mum pointsPlot the tray temperature at the time of in-4. stallation to determine the gap setting

Accurate gap setting at the time of installation is necessary for the proper operation of the expansion splice plates. The following procedure should assist the installer in determining the correct gap (see Figure 2):

Cable Tray Installation Guide

Installation of MPHusky Fiberglass Cable Tray should be made in accordance with the standards set by NEMA Publication VE-2 latest edition and National Electrical Code,

Article 392.

Always observe common safety practices when assembling tray and fittings. Installations ♦generally require some field cutting. Dust created during fabrication presents no serious health hazard, but skin irritation may be experienced by some workers.

Operators of saws and drills should wear masks, long sleeve shirts, or coveralls. ♦

Fabrication with Husky Fiberglass is relatively easy and comparable to working with wood. ♦Ordinary hand tools may be used in most cases.

Avoid excessive pressure when sawing or drilling. Too much force can rapidly dull tools and ♦also produce excessive heat which softens the bonding resin in the Husky Fiberglass, result-ing in a ragged edge rather than a clean-cut edge.

Field cutting is simple and can be accomplished with a circular power saw with an abrasive ♦cut-off wheel (masonry type) or hack saw (24 to 32 teeth per inch).

Drill Husky Fiberglass as you would drill hard wood. Standard twist drills are more than ad- ♦equate.

Any surface that has been drilled, cut, sanded or otherwise broken, ♦ must be sealed with a compatible resin.

Carbide tipped saw blades and drill bits are recommended when cutting large quantities. ♦

Support the Husky Fiberglass material firmly during cutting operations to keep material from ♦shifting, which may cause chipping at the cut edge.

Each tray section length should be equal to or greater than the support span. ♦

When possible, the splice should be located at quarter span. ♦

Fittings should be supported as per NEMA VE-2. ♦

Loading Information—Beam Loads: The charts below list the total allowable uniform load for various simple spans based on a minimum safety factor of 2. If the load is concentrated at the center span, multiply the load from the below charts by 0.5 and the corresponding deflection by 0.8. Note: All beam should be supported in a manner to prevent rotation at supports. Long, deep beams should be tied between supports to prevent twist.

Recommended Guideline: Published design loads are based on usage @ 70°F(21°C) and must be reduced for continuous exposure to higher temperatures. Refer to the chart at right for high tempera-ture applications.
