K24 LSZH Subway Signalling Cables

Application

The K24 LSZH Subway Signalling 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 55-624

Construction

Conductors
Solid copper conductor, 0.5/0.6/0.9 mm nominal diameter.

Insulation
Polyethylene insulation.

Cabling Element
Each two conductors are twisted together to form a pair.

Stranding
For cables less than 15 pairs, pairs are helically stranded in concentric layers to form the cable core. For cables from 21 to 112 pairs, pairs are stranded in concentric layers or bundles to form the cables core.

Core Wrapping
One or more synthetic long ribbons or tapes are arranged on the cable core.

Screen
Aluminium/Polyester tape.

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

Sheath
Fire retardant LSZH.

Optional

Armoured Cables: For armoured cable, one or more tape(s) is (are) helically applied with overlap on the screen to
form a bedding, and double steel tapes armour with a halogen-free fi re retardant outer sheath are applied on the bedding.
