Armoured Cables BS 5467 and BS 6346 Definition

Armoured Cable is the name given to electrical cable constructed with a layer of aluminum wire armour or steel wire armour. Cables in these standards are intended for use in supply of main electricity and can be found in underground systems, power networks, cable ducting, fixed installation in industrial areas, on exterior surface walls, building and similar applications.
