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.
