Steel Wire Armoured (SWA) cables represent one of the most robust and widely-used power cable designs for demanding installations. The 6943X (3-core) and 6944X (4-core) series are specifically engineered for applications wherever there is risk of mechanical stress or mechanical damage, including underground installations and outdoor environments. The steel wire armour layer serves as a protective barrier that significantly reduces the risk of cable pinching, impact damage, or other physical harm that could compromise electrical integrity. These cables are manufactured to BS 5467 standards and are suitable for direct burial without additional conduit protection, as well as surface installation on cable trays, baskets, clips, and in free air.

British Standard BS5467 specifies the requirements for low voltage armoured cables with thermosetting insulation rated at 600/1000V for fixed installations. These cables feature galvanised steel wire armour (SWA) for multi-core configurations and non-magnetic aluminium wire armour (AWA) for single-core applications. The standard encompasses cables with 1 to 48 cores, utilizing either plain annealed stranded copper (Class 2) or solid aluminium (Class 1) conductors per BS 6360/IEC 60228. The cross-linked polyethylene (XLPE) insulation ensures stable operation at maximum conductor temperatures of 90°C continuous and 250°C during short-circuit conditions.
