STEEL WIRE ARMOURED(SWA) is a power and auxiliary control cable, designed for use in mains supply electricity. It is one of the various protected electrical links – including 11 kV Cable and 33 kV Cable – and is found in underground systems and frameworks, cable networks, control systems, power networks, outdoor and indoor applications, and cable ducting.
Steel Wire Armoured Cable is designed to have mechanical protection, which is why the cable is often used for external use. The armour is used to reduce any risk of the cable getting pinched or damaged; the steel is used to protect the armoured cable. SWA cables are heavy, which makes them extremely difficult to bend; therefore they are most suited to underground cabling or fixed to outdoor walls using cable cleats.
