The main purpose of the shielded layer steel wire armoured cable is to improve the tensile strength and compressive strength. We use this type of cable in 11 kV and 33 kV underground & cable ducts electrical installations. It is a heavy-duty electrical power cable suitable for mains supply. The Steel armoured cable (SWA) is the most common type of armoured cable in electrical power distribution. The steel wire armour is abbreviated as SWA. Steel wire armoured cable has a strong steel wire conductor assembled with a layer of insulation. Now, we will discuss the types of armoured cables in detail. We can classify the armoured cables into steel wire, steel tape, aluminum wire and aluminum alloy. The structure of the armour guarantees maximum resistance to crushing, cutting, and wear. The armoured wire has higher tensile loads. The aluminium wire armour (AWA) and steel wire armour (SWA) provide the mechanical protection. Why are armoured cables used?įor outdoor installation or direct burial applications, there is a need of mechanical protection of electrical cables. The armour made of aluminium wires placed under the sheath to protect the conductor, and insulate the layers.
The armoured cable has an extra protective layer to keep it away from unwanted cut or damage. The armour provides the ultimate protection against electrostatic, magnetic, and common modes. It also avoids waste because the armoured cable are available in continuous rolls of convenient length. There is no need of rigid conduit pipe, such as threading, bending, making support when we use armored cable. Installation of armoured cable is fast and economical. It also prevents any internal irregularities from causing the release of dangerous energy levels to the outside in environments.Īrmoured cables are insulated with non-flame propagating thermoplastic compounds with low emission of smoke and toxic gases, covered with metal armour. The external vulnerable force to cables are rodents, and accidental impacts.
