Description

Single 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 11kV Cable and 33kV Cable - and is found in underground systems, power networks and cable ducting.

The typical construction of an SWA Cable can be broken down as follows:

  • Conductor: consists of plain stranded copper (cables are classified to indicate the degree of flexibility. Class 2 refers to rigid stranded copper conductors
  • 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 also be used as the circuit protective conductor ("earth wire") for the equipment supplied by cable.
  • Sheath: a black PVC sheath holds all components of the cable together and provides additional protection from external stresses.

The PVC version of SWA Cable, described above, meets the requirements and Standards

SWA Cable can be referred to more generally as Mains Cable, Armoured Cable, Power Cable and Booklet Armoured Cable. The name Power Cable, however, applies to a wide range of cables.
