IEC 0.6/1kV XLPE Insulation Steel Wire Armoured (SWA) Power Cable
Product Overview
The IEC 0.6/1kV XLPE Insulation Steel Wire Armoured (SWA) Power Cable is designed for fixed installation indoors and outdoors in cable ducts or directly in the ground. The cable is provided with mechanical protection and is therefore suitable for external use, direct burial, and areas where sudden mechanical stress is expected.
It is manufactured with a plain annealed copper or aluminium Class 2 conductor, XLPE insulation, and a galvanized steel wire armour (SWA) for multi-core versions. Single-core versions use aluminium wire armour (AWA). PVC inner and outer sheaths are standard, with LSZH polyolefin, flame retardant, and termite resistant options available.
Features & Benefits
