COMMITED TO RAILWAY SOLUTIONS.

Telecommunication and signalling cables.

COMMITED TO CABLE SOLUTIONS.

Our company PRAKAB PRAŽSKÁ KABELOVNA, s.r.o. was founded in 1921

and ranks among the leading European manufacturers of cables used

in energetics, telecommunications, construction industry and other areas.

Thanks to more than 90 years of experience and investment in modern

production equipment and testing systems we have become renowned Low

Fire Hazard Cable (LFHC)/Flame Retardant Non-Corrosive (FRNC) producers

and experts.

The membership of our company in SKB-GROUP also plays a vital role,

because the group as a whole puts emphasis on development, innovations,

team cooperation as well as exchange of experience.

We are fully committed to the solutions you're looking for.

From Schwechat and Prague to Nitra, Kiev and Saint Petersburg.

Ing. JAROMÍR SCHMID

Managing director

With the increasing demand for better citizens‘ mobility, it comes to a global expansion of the railwaynetwork, which offers fast and safe transportation of people and goods with regard to the environmentconservation and power saving.

The quality and safety of our products for railway transport is based on the long production traditionof telecommunication, signalling and power cables.

We offer cables• For underground and overhead installation• In self-supporting design with messenger rope/conductor• For installation in buildings• With improved properties when exposed to fire for installation in tunnels or in areas with high

concentrations of people.

Telecommunication and signalling cables from PRAKAB are used in a wide range of applications andvarious environments and conditions, especially in rail and public transport, telecommunicationnetworks and industrial electronics for control, telecommunication and signalling systems.

PRAKAB is a certified supplier to a number of European railway operators like OEBB, ČD, ŽSR, SBB,TCDD, DB, AŽD etc.

For high quality transmission of information and signals, it is important to protect cables againstthe influence of external electromagnetic fields that can interfere with signals transmitted by thecables. Such interference may destroyed the transmitted information or may even lead toa transmission of faulty signals.

REDUCTION FACTORReduction factor (RF) is an important cable screening parameter that defines the ability of the cableto reduce the intensity of external electromagnetic fields. The reduction factor is tested according toDIN VDE 0472-507 – Testing of cables, wires and flexible cords – Reduction factor. This parameterdepends on interference frequency and screening impedance. It lies in the interval from 0 to 1.0,with 0 standing for total interference elimination and 1 standing for an unscreened cable.

PRAKAB | TELECOMMUNICATION AND SIGNALLING CABLES


PRAKAB – YOUR SPECIALIST FOR TELECOMMUNICATIONAND SIGNALLING CABLES.

TELECOMMUNICATION CABLESGeneral use• Transmission of signals between communication devices• Fixed installation of indoor and outdoor distribution system in communication technology• Telecommunication core and access networks

Communication cables are divided into two main groups: indoor and outdoor cables.

Design

Indoor telecommunication cables• Copper core• Insulation (PE, PVC, halogen free polymer compound, silicone rubber)• Insulated conductors are twisted to basic elements (pairs or quads). A bundle of pairs or quads constitutes a cable core• Indoor covering (dielectric separation tape)• Screening (laminated aluminium foil)• Sheath (PVC, PE, halogen free polymer compound)

Outdoor telecommunication cables• Copper core• Insulation (PE foam skin, PE)• Insulated conductors are twisted to basic elements (pairs or quads). A bundle of pairs or quads constitutes a cable core• Cable core can be filled with water-blocking material• Indoor covering (dielectric separation tape)• Laminated sheath (double-sided laminated aluminium tape which is welded to the PE sheath)• Protective coating (aluminium wires, iron-zinc wires, iron tapes)• Outdoor protective coating (PE, PVC)

SIGNALLING CABLESGeneral use• Signal transmission between communication devices• Fixed cable installation of communication, control and signalling railway systems• Safety devices in road traffic (traffic lights, variable traffic signs, monitoring of traffic density)• Safety devices in railway traffic (traffic lights, traffic control, level crossings, information systems)• Underground railway devices (traffic control, information systems)

Design• Copper core• Insulation (PE)• Insulated conductors are twisted to basic elements (single cores, pairs or quads). A bundle

of pairs or quads constitutes a cable core• Indoor covering (dielectric separation tape)• Sheath (PVC, PE, halogen free polymer compound)• Mechanical protection (FE tape, FE wire)• Screening which determines a reduction factor (copper wires or copper tapes)• Outdoor protective coating (PE, PVC, halogen free polymer compound)

For the purpose of this booklet, we divide products into telecommunication and signalling cables,then we highlight separately LFHC (Low fire hazard cables) variants of both these types of cables.

WE MAKE NO COMPROMISES WHEN IT COMES TO QUALITY.QUALITY IS OUR TOP PRIORITY AND IS GUARANTEED BY BOTH

OUR STRINGENT IN-HOUSE TESTING AND INDUSTRY CERTIFICATION.

COMMITTED TO QUALITY.


PRAKAB | CERTIFIED QUALITY

LFHC TELECOMMUNICATION AND SIGNALLINGCABLES WITH REACTION TO FIRE These cables are divided into two main groups: without functional integrityand with 30–90 minutes functional integrity.

Cables without functional integrity

General use• Transmission of analog and digital data• Fixed installation of indoor distribution system in communication technology• To protect people and valuable equipment in the event of fire• If it is required a release of a small amount of heat and smoke and no dripping of flaming

particles

Design• Copper core• Insulation (halogen-free polymer compound)• Insulated conductors are twisted to basic elements (pairs or quad). These elements are stranded

to the cable core• Indoor covering (halogen-free plastic tape)• Screen (plastic laminated aluminium tape with drain wire)• Indoor covering (halogen-free polymer compound)• Sheath (halogen-free polymer compound)

Cables with functional integrity

General use• Transmission of analog and digital data• Fixed installation of indoor distribution system in communication technology• Can be used for variety of transmission systems including ADSL2+ and VDSL2• To protect people and valuable equipment in the event of fire • If it is required a release of a small amount of heat and smoke and no dripping of flaming

particles• Siutable for hotels, hospitals, underground railways, airport etc.• If functional integrity of entire cable installation must be maintained in the event of fire

Design• Copper core• Insulation (silicone rubber, foam skin silicone rubber)• Insulated conductors are twisted to basic elements (pairs or quad). These elements are stranded

to the cable core• Indoor covering (halogen-free plastic tape)• Screen (plastic laminated aluminium tape with drain wire)• Indoor covering (halogen-free polymer compound)• Sheath (halogen-free polymer compound)
