MV POWER CABLE APPLICATION
MV power cable is used for power distribution networks; also for connection to generation units and plant and process connection. The mv cable could be laid directly in ground, outdoors, indoors and in cable ducts.
MV POWER CABLE CHARACTERISTICS
The ambient temperature under installation should not be lower than: 0 °C
When the armored single core cable used for Alternative Current(AC) system, the armour material should be non-magnetic. |
