SWA Copper Armoured Electrical Cable 600/1000V 2 3 4 5 Core

Application

Steel Wire Armoured (SWA) Cable features a robust construction with a black PVC sheath, XLPE insulation, copper conductors, and steel wire armouring. Designed for mains electricity supply, it is widely used in power networks, underground installations, and both external and internal wiring, including residential mains connections. The steel wire armouring enhances durability, making it ideal for direct burial by protecting against mechanical damage. The XLPE insulation offers excellent resistance to heat, chemicals, fluids, and UV exposure, ensuring reliable performance in harsh environments.
