185mm² 3 Core Steel Wire Armoured (SWA) Cable is a heavy-duty low voltage (LV) power cable designed for distributing mains electricity in a wide range of industrial, commercial, and infrastructure environments. It features stranded copper conductors, XLPE insulation, steel wire armouring, and a robust black PVC outer sheath, ensuring durability, safety, and high performance in both underground and surface-mounted installations.

This cable is especially suited for direct burial, thanks to the steel wire armour (SWA) which offers excellent mechanical protection against external impact, rodent damage, and environmental stress.

Key Features

  • Conductor: Stranded plain copper (or aluminium on request)

  • Insulation: XLPE (Cross-Linked Polyethylene), rated at 90°C

  • Armour: Galvanized steel wire armour (SWA) for mechanical protection

  • Sheath: Black PVC (UV resistant), available in specialized variants

  • Rated Voltage: 600/1000V

  • Standards: BS 5467, IEC 60502-1, IEC 60228

  • Flame Retardant: IEC 60332-1-2 compliant

Applications

  • Underground power distribution

  • Outdoor fixed installations

  • Mains cable to buildings or switchboards

  • Industrial power networks

  • Cable tray or ducted installation in harsh environments
