Armoured Cables

Armoured cable is the name given to any electrical cable constructed with a layer of aluminium wire armour or steal wire armour. The armour sits below the sheath of the cable to provide protection for the conductor and insulating layers. When electrical cable is required for outside use or in direct burial projects, it must have mechanical protection. Aluminium wire armour or AWA, and steel wire armour or SWA provide such protection as well as enabling the cable to withstand higher pulling loads.

AWA and SWA are used in the power cables.

SWA
Steel Wire/strip Armoured Cable or SWA Cable is a hard-wearing mains electricity cable with class 2 stranded copper conductors, XLPE (Cross-Linked Polyethylene) insulation, PVC (Polyvinyl Chloride) bedding, aluminium or steel wire armour and a black PVC sheath. The voltage rating of an SWA Cable is 600/1000V.

AWA
Aluminium Wire/strip Armoured Cable or AWA Cable is a hard-wearing mains electricity cable with class 2 stranded Aluminium conductors, XLPE (Cross-Linked Polyethylene) insulation, PVC (Polyvinyl Chloride) bedding, aluminium or steel wire armour and a black PVC sheath. The voltage rating of an SWA Cable is 600/1000V.

Applications:
Armoured cables used in everything from transmission, power and distribution networks and the renewable energy sector to the oil, gas and petrochemical, water treatment, transport industries, underground, outdoor & indoor applications.
