    ZPFU & ZPFU-SH Main & Local Signalling Cables (Ordinary Non-Electrified or DC Electrified Lines)

    • ZPFU & ZPFU-SH Main & Local Signalling Cables

    Application

    The cables are designed for the main signalling circuits of 1500V DC electrifi ed lines.

    Standard

    SNCF CT 445

    NF F 55-698

    Cable Construction

    Conductors : Solid annealed copper, 1.0mm sq nominal cross section area.

    Insulation : Solid polyethylene.

    Cabling Element : Two conductors are twisted to form a pair.

    Stranding : Pairs are helically stranded to form the cable core.

    Core Wrapping : Plastic tape(s) with overlapping.

    Inner Sheath : PE. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).

    Mechanical Protection : Two helically applied steel tapes (0.15, 0.2/0.5mm, depending on pair count).

    Outer Sheath : PE/PVC. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).

    Remark : ZPFU : PE/PVC Sheath; ZPFU-SH : LSZH Sheath.
