MV Cable Specification
Cable Conductor – Compact circular stranded copper conductor complying with BS EN 60228 Class 2.
Conductor Screen – Extruded semi-conducting compound bonded to the insulation and applied in the same operation as the insulation.
XLPE Insulation – Extruded cross-linked polyethylene (XLPE) suitable for operation at a conductor temperature of 90°C.
Insulation Screen – Extruded semi-conducting compound applied in the same operation as the insulation. Cold strippable screens are supplied as standard but fully bonded screens may be provided if specified.
Metallic Copper Screen – Copper tape screens applied overlapped to provide an earth fault current path.
Cable Laying Up – Three cores laid up with polypropylene string fillers to form a compact circular cable.
Cable Armouring – Single layer of galvanised circular steel wires.
Cable Oversheath – Extruded black polyvinyl chloride (PVC) or Low Smoke Zero Halogen (LSOH) compound is supplied as standard. Alternative materials may be provided if specified e.g. medium density polyethylene (MDPE).
