Railway Cables

K13 PVC Subway Signalling Cables for
Metro/Local Trains/Tramlines

Application

The cables are designed for remote control and teletransmission in underground railway networks. The cables can be laid in channel, cable tray, or on hook supports, along suburban railway lines electrifi ed at maximum 1500V DC

Standards

● AFNOR NF F 55-633

Construction

Conductors
Solid copper conductor, 0.6/0.8/1.0/1.2 mm nominal diameter.

Insulation
Polyethylene insulation.

Cabling Element
Pair/Quad.

Stranding
4-pair cables are composed of pairs, while other cables are composed of star quads.

Spare Pairs
Spare pairs may be provided according to capacity of cables.

Core Wrapping
One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap.

Screen
Aluminium/Nylon tape bonded with a special PVC sealing sheath or Aluminium/PE tape bonded with a
halogen-free fi re-retardant sheath.

Drain Wire
A tinned copper drain wire, 0.5mm nominal diameter.

Bedding
Several glass silk tapes are helically laid with an overlap to form bedding.

Armour
Two helically applied steel tapes.

Outer Sheath
LSPVC.
