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.

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
