SWA Cable Size

What is SWA Cable ?

SWA Cable or Steel wire armoured cable is a hard-wearing cable made up of Black PVC Sheath, xlpe insulation, copper conductors and steel wire armouring. SWA Cable is designed for mains electricity for laying underground, power networks, incoming mains to homes amongst a host of other applications externally and internally.

SWA Cable is also handy as it allows the user to use the cable for direct burial and the armour enables the cable to withstand higher pulling loads. XLPE insulation is resistant to a number of different fluids, chemicals and has good heat stability.

SWA Cable Construction：

Plain Annealed Stranded Copper for the cores/conductors

XLPE (Cross-Linked Polyethylene) for the insulation

PVC (Polyvinyl Chloride) for the sheathing and bedding

Steel Wire for the armouring that protects the insulating layers beneath.

SWA Cable Classification :

According to the different insulating materials, SWA Cable is divided into PVC SWA cable, XLPE SWA cable and XLPE SWA LSF cable. The application of XLPE swa cable is MV armour cable and LV armour cable. And its maximum operating temperature is 90 degrees Celsius. PVC swa cable application is just LV armour cable. And its maximum operating temperature is 70 degrees Celsius. The insulation material of the XLPE SWA LSF cable is made of low-smoke and halogen-free XLPE insulation.
