Armoured cable is essential in harsher environments as it's tough and hard wearing. If a standard cable is run through areas such as building sites or a factory, it may increase the chance of power loss or electrical cut outs. The armoured cable can be used for numerous applications which require an uninterrupted and worry free power connection.
The best use of this cable would be if the intended application is likely to be on a rough surface, or is situated in areas where there is high traffic and risk of debris striking the power cable. This would be the most beneficial. As an example, some of the applications for using SWA cable include:
Steel wire armoured cable (SWA) is a highly reinforced power cable. It will supply a continuous flow of electricity to the intended target, due to the galvanized steel overlapping the centre cable. Each cable is built up of numerous copper cores, followed by XLPE insulation of the cores. The insulated cores are then protected by a layer of PVC bedding, which is secured by steel wire. Finally, a thick outer layer of PVC covers the entirety of the cable.
