WHAT IS AN SWA CABLE?

SWA is a power and auxiliary control cable, designed for use in mains supply electricity. It is one of the various protected electrical links – including 11 kV Cable and 33 kV Cable – and is found in underground systems and frameworks, cable networks, control systems, power networks, outdoor and indoor applications, and cable ducting.

SWA Cable Multi Core (Steel Wired Armoured Cables)

A multi core swa cable, is a cable with a number of cores, steel wire armour is only used on multi core cables.

2 Core SWA Armoured Cable A two core steel wire armoured cable or SWA Cable is live and neutral for Class II and Double Insulated appliances which do not need earth connection.

3 Core SWA Armoured Cable Three core SWA Cables are live, neutral and earth, unlike two core which is only live and neutral. Three core cable is for Class I or Single Insulated which must have earth connections.

4 Core SWA Armoured Cable Four core cables are perfect for low voltage or low current signal applications. Made of 4 copper individual colour coordinated cables hence the name four core cable.

5 Core SWA Armoured Cable The five core SWA Cable is most commonly used in low-voltage transmissions and uses a three-phase line with one zero line for the power supply.

7 Core SWA Armoured Cable The seven core cable prime purpose is for low-voltage connections with a max of normal 50Vdc. Each core is made from copper conductors within the steel armouring.

Construction of an SWA Armoured Cable

The typical construction of SWA PVC (Polyvinyl Chloride) cable is as follows:

Conductor: plain stranded copper or aluminium

Insulation: XLPE(Cross-Linked Polyethylene)

Bedding: PVC(Polyvinyl Chloride)

Armouring: SWA(Steel Wire Armour)

Sheath: PVC(Polyvinyl Chloride)

Sheath Colour: Black(CarbonloadedforUVstability)

Voltage Rating: 600/1000V, 6.35/11kV and 19/33kV.
