120mm 4 Core Steel Wire Armoured SWA Cable Application

120mm 4 Core Steel Wire Armoured SWA Cable made up of a black PVC sheath, XLPE insulation, copper conductors and steel wire armouring. This type of cable is designed for mains electricity in various applications, including laying underground, power networks, incoming mains to homes amongst a host of other uses externally and internally.

120mm 4 Core Steel Wire Armoured SWA Cable is suitable and often used for direct burial, with the steel wire armouring providing further protection from external damaged. The XLPE insulation is resistant to a number of different fluids, chemicals and has good heat stability, as well as being UV Resistant.
