    K24 LSZH Subway Signalling Cables

    • K24 LSZH Subway Signalling Cables
    • K24 LSZH Subway Signalling Cables

    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.

    Standard

    • AFNOR NF F 55-624

    Cable Construction

    • Electrical Characteristics at 20℃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.

    Minimum Insulation Resistance MΩ.km 5000 5000 5000
    Maximum Operating Voltage V 200 200 400
    Maximum Permissible Current A 0.25 0.35 0.80

    Mechanical and Thermal Properties

    • Minimum Bending Radius: 7.5×OD (unarmoured); 10×OD (armoured)
    • Temperature Range: -40℃ to +60℃ (during operation); -20℃ to +50℃ (during installation)
