    Application

    They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.

    Standards

    Basic design adapted to IEC 60502-2

    Construction

    Conductor : Plain annealed copper wire, stranded according to IEC/BS EN 60228 class 2..

    Conductor Screen : Extruded layer of semi-conducting cross-linkable compound is applied over the conductor and shall cover the surface completely.

    Insulation : Extruded cross-linked compound type (XLPE)

    Insulaton Screen : Extruded layer of semi-conducting cross-linkable compound is applied over the insulation.

    Metallic Screen : The metallic layer shall be applied as a collective screen. The metallic screen shall consist of either copper tapes or a concentric layer of copper wires or a combination of tapes and wires.

    Separation Sheath : Thermoplastic PVC compound.

    Armour : Aluminium tape or Aluminium wire.

    Outer Sheath : Thermoplastic MDPE compound Type ST7 according to IEC 60502-2.The overall cable design will be more suitable for wet locations.
