Single Core Steel Wire Armoured Cable

Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.
 
Construction of SWA cables:
 
Conductor: consists of plain stranded copper
 
Insulation: Cross-linked polyethylene (XLPE) is used in a number of power cables because it has good water resistance and excellent electrical properties. Insulation in cables ensures that conductors and other metal substances do not come into contact with each other.
 
Bedding: Polyvinyl chloride (PVC) bedding is used to provide a protective boundary between inner and outer layers of the cable.
 
Armour: Steel wire armour provides mechanical protection, which means the cable can withstand higher stresses, be buried directly and used in external or underground projects. The armouring is normally connected to earth and can sometimes be used as the circuit protective conductor for the equipment supplied by cable.
 
Sheath: PVC Black - is available in many compound forms but those used in cable manufacture are plasticized to allow extrusion techniques and subsequent flexibility. It has good ageing and mechanical properties.
 
Application:
Designed for use in cathodic protection systems. These cables are provided with mechanical protection are therefore suitable for external use and direct
burial.

Voltage: 600/1000V,
Temperature range: -40℃ to +90℃
Relevant Standards:
 
Conductor: BS6360
Sheath: BS6746 Type G
