    • SW-CLT Switching Centre Cables

    Application

    The cables are used as block cables for railway. The cables are suitable for connection between local switching centre and the trackside and signalling equipments.

    Standard

    • CFF: I-EB-SK 3001.82.1000

    Cable Construction

    • Electrical Characteristics at 20℃Conductors: Class 1 solid copper, 1.0/1.5/2.2mm nominal diameter
    • Insulation: Solid polyethylene.
    • Cabling Element: Four conductors are twisted together to form a quad.
    • Inner Sheath: PE sheath.
    • Armour: Double galvanized steel tapes of 0.15mm.
    • Outer Sheath: PE/LSZH sheath.
    • Optional:
