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.
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.

Building wire is generally used in house fixed wiring. It is PVC insulated unsheathed electric wire. The onstruction is CU/PVC.
How do I know if a cable is compliant with standards?
Look for certification marks or labels on the cable, such as those from IEC, UL, or other relevant regulatory bodies that indicate compliance with safety and performance standards.
What are armoured cables?
Armoured cables have an additional layer of protection (usually metal) to prevent physical damage. They are often used in harsh environments or where cables may be exposed to impact.
Conductor Structure of Power Cable
1. Conductors comply with IEC, AS/NZS and BSI standard requirements
2. The conductors of multi-core have different shapes. The single-core is circular. The shape of Multi-core cable with size up to and 35m2 can be circular, semicircular and fan-shaped, the conductor with size over and 50m2 are circular and semicircle.
3. A single core is allowed with size below 16m2. Conductor More than 25m2 are multi strands.
