MV Cable Specification

33kV MV Cables BS6622/BS7835 - Single Core XLPE AWA Stranded Copper Conductors

1. 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.

2. XLPE Insulation – Extruded cross-linked polyethylene (XLPE) suitable for operation at a conductor temperature of 90°C.

3. 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.

4. Metallic Copper Screen – Copper tape screens applied overlapped to provide an earth fault current path.

5. Cable Bedding – Extruded black polyvinyl chloride (PVC) or Low Smoke Zero Halogen (LSOH) compound is supplied as standard. Alternative materials may be provided if specified.

6. Cable Armouring – Single layer of circular aluminium wires.

7. 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).
