    PE Insulated Air Core/Jelly Filled Star Quad Railway Signalling Cables (RF 0.1)

    Application

    The cables are designed to give good protection to the core against inductive interference (RF=0.1).The cables are used for outdoor signaling equipment.

    Standards

    • RENFE E.T. 03.365.051.6

    Construction

    Conductors

    Solid annealed bare copper 0.9/1.4mm as per ASTM B-3/class 1 of IEC 60228

    Insulation

    Solid polyethylene as per ASTM D 1248/IEC 60708

    Cabling Element

    Four insulated conductors are twisted together to form a quad

    Cable Core Assembly

    The cores are cabled together in concentric layers to form the cable core. Units are identified by colour coded binders

    Core Wrapping

    One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap

    Electrostatic Screen

    One layer of copper wires 0.12mm is applied helically

    Bedding

    PE or LSZH

    Electrostatic Armour

    Two steel tapes of 0.5mm are helically applied with gap. The outer tape will cover the gap left by the inner one

    Sheath

    PE/PVC or LSZH

    Ripcord

    Nylon ripcord may be placed parallel to the cores to facilitate sheath removal
