    G7622 Trackside Communications Cables

    Application

    The cables are designed for installation in trackside bracket runs and for use within railway equipment rooms within open locations (type 1) or in subsurface tunnels and underground locations (type 2).

    Standard

    • LUL Spec G7622 A1 type 1 (for PVC sheath)
    • LUL Spec G7622 A1 type 2 (for LSZH sheath)

    Cable Construction

    • Core IdentificationConductors: Solid plain copper, 0.63/0.9 mm nominal diameter.
    • Insulation: Cellular polyethylene.
    • Cabling Element: Four insulated conductors are twisted together to form a quad.
    • Stranding: Conductors are helically stranded in concentric layers.
    • Core Wrapping: Plastic tape (s) with overlapping.
    • Moisture Barrier: One laminated sheath made of aluminium tape (0.15mm thick) coated with PE-Copolymer on at least one side is applied with longitudinally overlap.
    • Outer Sheath: LSZH sheath, coloured violet.
    • Optional

    • Type 1 Cables: For type 1 cables, additional foil (at least one polyester tape) and PVC sheath are applied over the LSZH sheath. (VDE Code: A-02Y(L)HY)
    • Armoured Cables: Corrugated steel tape armour is applied with an overlap over LSZH sheath. An outer LSZH sheath is applied over the armour. (VDE Code: A-02Y(L)H(SR)H)
