BS6622 Cable
Armoured cables with thermosetting insulation - 3.8/6.6kV to 19/33kV - manufactured in accordance with British Standard BS6622
We offer a comprehensive range of Medium Voltage (MV) BS6622 cables, with the manufacture quality and compliance verified by The Cable Lab to provide assurances for critical power projects.
BS6622 Single Core and BS6622 Three-Core Cable Specification
British Standard BS 6622 sets out the specifications and required tests for armoured cables (single core AWA and three core SWA) for cables designed for use in fixed installations including networks and industrial installations. Across all voltages, the most commonly specified is the BS6622 11kV cable.
BS6622 cable construction
British Standard BS6622 specified the following cable construction:
| Conductor(s) | Stranded copper (Class 2), Aluminium stranded (Class 2) or solid (class 1) |
| Insulation | Cross-linked Polyethylene (XLPE) Type GP8 or Cross-linked Ethylene Propylene Rubber (EPR) Type GP7 |
| Insulation screen | Extruded semi-conductive layer of cross-linkable polymer or combination of semi-conductive layer and semi-conductive tape |
| Metallic screen | Metallic screening layer of copper wire or copper tape |
| Inner sheath | Polyvinyl Chloride (PVC) bedding material |
| Armour | Metallic armour to consist of aluminium (Al) wires for single core cables or galvanised steel wires for three core cables |
| Outer sheath | Polyvinyl Chloride (PVC) compound or medium density Polyethylene (MDPE) |
BS6622 cable selection
According to this Standard, systems are divided into three categories in order to facilitate the cable selection and the required voltage rating. These are:
| Category | Applications |
|---|---|
| A | Systems where phase conductors that comes into contact with earth or an earth conductor are disconnected within 1 minute |
| B | Systems which continue to operate under fault conditions of up to 8 hours (not exceeding 125 hours per annum) |
| C | Systems not falling under A or B |
Cables manufactured in accordance with BS6622 are designed to be installed in air or to be buried in free-draining soil. Consultation with the manufacturer is required for installation in other conditions.
