The XLPE insulated heavy duty cables were introduced worldwide in mid sixties. These cables have overcome the limitations of PVC Insulated Cables such as thermal degradation, poor moisture resistant and thermoplastic in nature.

The advantages of XLPE Insulated cables in comparison to PVC insulated cables are as under:

A. Technical Advantages :

1. Higher current rating, higher Short Circuit Rating Approx 1.2 times that of PVC.

2. Thermosetting in nature.

3. Higher insulation resistance – 1000 times more than PVC cables.

4. Higher resistance to moisture.

5. Better Resistance to surge currents.

6. Low Dielectric Losses.

7. Better resistance to chemicals.

8. Longer service life.

9. Comparatively higher cable operation temperature 90°C and short circuit temperature 250°C.

B. Commercial Advantages:

1. Lower laying cost because of comparatively smaller diameter of cable and lighter weight*.

2. Lower installation charges as the diameter of cable is comparatively lesser with smaller bending radius, requiring less space requirement for laying of cables.

3. **One size lower cable can be used as compared to PVC insulated cable.

* Density of XLPE is lower than PVC

**For longer cable length voltage drop shall be considered

Advantages of Polycab XLPE Cables

Selection of Cables

Power Cables are generally selected considering the application. However, following factors are important for selection of suitable cable construction required to transport electrical energy from one end to the other.

1) Maximum operating voltage,

2) Fault Level,

3) Load to be carried,

4) Possible overloading duration & magnitude,

5) Route length and voltage drop.

6) Mode of installation considering installation environment such as ambient & ground temperature chemical & physical properties of soil.

7) Flame retardant properties.

All sizes of POLYCAB XLPE cables are designed to standard operating conditions in India and abroad.Thestandardsadoptedareconsideringthegeographical/climaticalconditionsand general applications of power for utilities, distribution and generation purposes.

The cables are manufactured conforming to Indian & International cables specifications for XLPE Insulated cables. Customer specific requirements can also be met.

POLYCAB RECOMDATIONS FOR CURRENT RATINgS

1. The values given in the table are valid for on circuit in a three phase system under conditions specified. For grouping cables rating factors must be used.

2. The current carrying capacities mentioned in POLYCAB technical data are intended as a guide, to assist operating engineers in selecting cables for safety and reliability.

3. Basic assumptions and condition of installation: * Ambient ground Temperature : 30° C * Ambient air Temperature: 40° C * Depth of Cable Burial : 1.0 m * Thermal resistivity of soil : 150°C.Cm/W

4. Single Core Cables are installed as indicated in the table, spacing between cables in flat formation is as indicated.

5. For 3 and 4 core cables, it is usual to assume the same current carrying capacity for 4 core cables as for 3 core cables. Our calculated values are based actually on 3 core cables. These values are suitable with enough accuracy also for 4 cables in most cases. Only for large 4 core cables in air the values are too conservative, due to the large cable surface and consequent high heat dissipation factor.

6. To obtain the maximum current carrying capacity of a cable operating at different conditions from the standard. Various rating factors are to be multiplied as follows:

Ia = K Is (in Amperes) Where

Ia = Current Rating at actual Operating Conditions (amperes) Is = Current Rating at Standard Operating Conditions (amperes) K = Rating Factor as applicable

Note: R Minimum Permissible bending radius of cable.

Handling, Storage and Laying of Polycab Cables

C. PRE- INSTALLATIONTo ensure safety during cable installation, following shall be checked prior to installation.1. The cable selected is proper for

designed application.2. The cable has not been damaged in

transit or storage. Review all applicable state and national codes to verify that the cable chosen is appropriate for the job. Also consultyour local electricity authority. Next, you must identify any existing cable damage and prevent any further damaged from occurring. This is done through proper cable inspection, handling and storage.

D. INSTALLATION & LAYINg Mechanical stresses during installation are generally more severe than those encountered while in service. Thus care should be taken as regards to the following while installation and laying of cables.1. Polycab recommend the laying and

installation of cables as per IS: 1255/84.

2. Care shall be taken during laying to avoid sharp bending, and twisting.

3. Cable shall be un wound from the drum by lifting the drum on the center

4. Shaft supported both ends with suitablejacks/stands.

5. Under no circumstances the cable winding shall be lifted off a coil or drum lying flat at the flanges. This would cause serious twist and damages.

6. Suitable protection shall be provided to the cables against mechanical damages, it includes covers, pipes etc.

E. RECOMMENDED MINIMUM BENDINg RADIUS FOR HEAvY DUTY CABLES. Single Core : 20 x D

Multicore : 15 x D

Where D = Diameter of cable in mm

F. RECOMMENDED SAFE PULLINg FORCE WITH STOCKINgS:a) For Unarmoured Cable : P = 5 D2

b) For Armoured Cable : P = 9 D2

Where P = Pulling Force Where D = Diameter of cable in mm

g. RECOMMENDED SAFE PULLINg FORCE WHEN PULLED WITH PULLINg EYE :a) ForAluminiumConductor:30N/mm2

b) ForCopperConductor:50N/mm2
