BS6622 Cable

BS6622 Cable Overview

BS6622 cables are armoured cables with thermosetting insulation, designed for medium voltage applications ranging from 3.8/6.6kV to 19/33kV. These cables are manufactured in compliance with British Standard BS6622, ensuring high-quality performance for critical power projects.

Key Features

• Voltage Range: 3.8/6.6kV to 19/33kV
• Applications: Fixed installations, including networks and industrial setups
• Compliance: Verified by The Cable Lab for quality and compliance

Cable Construction

1. Conductor: Stranded copper (Class 2), aluminium stranded (Class 2), or solid (Class 1)
2. Insulation: Cross-linked Polyethylene (XLPE) or Ethylene Propylene Rubber (EPR)
3. Insulation Screen: Semi-conductive polymer or tape
4. Metallic Screen: Copper wire or tape
5. Inner Sheath: PVC bedding material
6. Armour: Aluminium wires (single core) or galvanised steel wires (three core)
7. Outer Sheath: PVC or MDPE (Medium Density Polyethylene)

Applications

• Suitable for direct burial, external installations, and internal installations (PVC sheathed cables are CPR compliant for internal use).
• Designed for air installations or burial in free-draining soil.

System Categories

BS6622 cables are categorised based on system requirements:

• Category A: Systems disconnecting within 1 minute upon contact with earth
• Category B: Systems operating under fault conditions for up to 8 hours
• Category C: Systems not covered under A or B

Available Variants

• Single Core AWA/PVC
• Three Core SWA/PVC
• Low Smoke Zero Halogen (LSZH) options for public spaces and higher CPR classifications

Technical Support
