6.6kV Cables | single core Medium Voltage

Thorne & Derrick distribute MV HV Cables for medium and high voltage electrical systems, typically distributing 6.6kV-11kV-33kV power – we provide competitive prices for MV & HV Cables and cable accessories including joints, terminations and connectors from extensive stocks to UK and international destinations. Complete range of Cold Shrink cable accessories from stock are available for the jointing and terminating of 6.6kV cables into electrical equipment including switchgear, transformers and overhead lines.

Single core and 3 core power cables with XLPE insulation, copper tape screens and wire armour (AWA Single | SWA 3 Core) are available with stranded copper or aluminium conductors for 6.6kV, 11kV, 15kV, 22kV and 33kV voltage classifications – manufactured in accordance with BS6622 (PVC Sheath) or BS7835 (Low Smoke Zero Halogen Sheath).

Should you require customer service or technical support to enable the selection of the correct medium voltage cable please contact us.

6.6kV Cables

MV Cable Specification

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).
