Application

Their aluminium wire armour (AWA) for single core cables and steel wire armour (SWA) for multicore cables provide robust mechanical protection making these MV cables suitable for direct burial in the ground. These armoured MV mains power cables are more commonly supplied with copper conductors but they are also available with aluminium conductors upon request to the same standard. The copper conductors are stranded (Class 2) whereas the aluminium conductors are compliant to the standard using both stranded and solid (Class 1) constructions.

Operating characteristics

1. Laying temperature: ≥0°C;

2. Cable conductor long-term allowable working temperature: PVC insulated ≤70°C, XLPE insulated ≤90°C;

3. Maximum operating temperature in case of short-circuit: PVC insulated ≤160°C, XLPE insulation ≤ 250°C;

4. Cable bending radius:
