Home >> Product >> Railway Cable >> Signalling & Control CableK23 LSZH Subway Signalling Cables for Metro/Local Trains/Tramlines
Applications :
- 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 :
- NF F 55-623
 |
 |
Construction :
- Conductors : Copper wire, 0.6, 0.8, 1.0 or 1.2 mm nominal diameter.
- Insulation : Solid polyethylene.
- Cabling Element : Four conductors are twisted to form a star quad. For 1 & 4 pair cables,conductors shall be twisted in pairs
- Stranding : Quads are stranded in helically laid concentric layers or units to form the cable core.
- Core wrapping : Plastic tape(s) with overlapping.
- Moisture barrier : One laminated sheath made of aluminium tape coated with PE-Copolymer on at least one side is applied with longitudinally overlap.
- Inner sheath : LSZH fire retardant compound.
- Armour : Two helically applied steel tapes.
- Outer sheath : LSZH fire retardant compound.
