    Digicode 30KHz Indoor Signalling Cables

    Application

    The cables are designed for transmission of track circuit digicode signals up to 30 kHz in electrified lines.

    Standard

    • EN 50266-2-4 & IEC 60332-3(Fire performance)
    • EN 50268-2(Smoke density)
    • EN 50267-2-1(Halogen content)
    • EN 50267-2-2(Gases acidity)
    • EN 50265-2-1, IEC 60332-1, NF C 32070 Cat C2 compliant (for PVC sheathed cables)

    Cable Construction

    • Electrical Characteristics at 20℃Conductors: Solid Annealed copper, 1.4 mm nominal diameter (0.6 mm for the auxiliary pair).
    • Insulation: Polyethylene.
    • Cabling Element: Two insulated conductors are twisted together to form a pair.
    • Stranding: Pairs are helically stranded to get the cable core.
    • Core Wrapping: Plastic tape(s) with overlapping.
    • Inner Sheath: Low density polyethylene.
    • Moisture Barrier: Copolymer coated laminated aluminium tape.
    • Intermediate Sheath: LSZH fi re retardant compound. PE or PVC option can be offered upon request.
    • Mechanical Protection: Two helically applied steel tapes.
    • Outer Sheath: LSZH fi re retardant compound. PE or PVC option can be offered upon request.
