K23 LSZH 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
● 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 fi re retardant compound.
Armour
Two helically applied steel tapes.
Outer Sheath
LSZH fi re retardant compound.
