SWA Armoured Power Cable

SWA Armoured Power Cable

BS5467 Cu/XLPE/PVC/SWA/PVC 0.6/1kV

Cable Application

Cu/XLPE/PVC/SWA/PVC power cable may be used for fixed installation indoors and outdoors in cable ducts or directly in the ground. The steel wire armoured cable is the accepted standard for underground installations, designed for use in mains supply electricity. These cables are provided with mechanical protection and are therefore suitable for external use, direct burial and areas where sudden mechanical stress are expected. SWA Cable is one of our most popular cables from small projects in the garden for landscapers to large infrastructure projects. Click to view some our occasionally blogged SWA cable projects.
