These include low voltage and medium voltage SWA steel wire armour 3 core cable, and all sizes of these widely used armoured power cables with current ratings up to 33kV. For single core cables, aluminium wire armour - AWA - is used to prevent induced current in the armour. Armoured power cables are available with both copper and aluminium conductors as required.
The armour provides additional protection where mechanical stress has the potential to cause damage to the cable, such as direct burial, outdoors or underground. The armour also enables the cable to withstand higher pulling loads. It should be noted, however, that the armour provides no protection for climatic conditions.
Armoured cables are often referred to as steel wire armoured cables, SWA cable, mains power cable, single core power cable, and multi-core booklet armoured cable.
Stranded circular compacted copper or aluminum conductor with a semi-conducting layer as conductor screen, XLPE insulated, and a semi-conducting layer as non-metallic insulation screen, copper tape or wire as metallic insulation screen. PVC sheathed. Meets IEC 60502.
These cables are suitable for direct burial or for installation on trays or in ducts.
