Armoured cables are often referred to as steel wire armoured cables, SWA cable, mains power cable, single core power cable, and multi-core booklet armoured cable. Armoured cables are insulated with non-flame propagating thermoplastic compounds with low emission of smoke and toxic gases, covered with metal armour.
The armoured cable has an extra protective layer to keep it away from unwanted cut or damage. The armour made of aluminium wires placed under the sheath to protect the conductor, and insulate the layers. The armour provides additional protection where mechanical stress has the potential to cause damage to the cable, such as direct burial, outdoors or underground. The armour also enables the cable to withstand higher pulling loads. It should be noted, however, that the armour provides no protection for climatic conditions.
For outdoor installation or direct burial applications, there is a need of mechanical protection of electrical cables. The aluminium wire armour (AWA) and steel wire armour (SWA) provide the mechanical protection. The armoured wire has higher tensile loads.
The structure of the armour guarantees maximum resistance to crushing, cutting, and wear.
