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.
