MV Underground Power Cables Outdoor Energy IEC 60502 BS6622- 6/10 6.35/11kV
6/10kV 12/20kV 18/30kV MV Underground Power Cables Outdoor Energy IEC 60502 BS 6622 6.35/11kV 12.7/22kV 19/33kV SWA Cable
MV Underground Power Cables Outdoor Energy BS 7835 - 6.35/11kV SWA 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:

Note: The single-core armored cables are used for the D.C. system only. If used for the A.C. system, the magnetic isolation should be applied to the steel armor wires of non-magnetical materials that should be used.
3 Operating characteristics - Rated power-frepuency voltage U0/U: 6.35/11kV. - Max.admissible operating temperature of the conductor:90ºC. - Max. short-circurt temperature of conductor shall not exceed 250ºC. (5s maximum duration) - The ambient temperature under installation should not below 0ºC. - The bending radius of a single-core cable should not less than 20 times of the cable diameter. The bending radius of a multi-core cable should not less than 15 times of the cable diameter.
