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.

MV Cables Construction

Cable models, names, and laying conditions 

Armoured 3-core cable with XLPE insualtion. Rated voltage 6/10 KV 6.35/11KV

Cable Data

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.
