MV Cable Specification

1. Cable Conductor
6.6kV MV Cables BS6622 BS7835 - Single Core XLPE AWA Stranded Copper Conductors

6.6kV Cables

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/jacket

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).
