| Medium VOLTAGE CABLES |
|
|
| 12/ 20kV or 12.7/ 22kV XLPE Insulated, Longitudinally Sealed , Single Core Cables with Copper Conductor |
|
 Application： |
|
|
| These are cables with low dielectric loses, used in energy networks with sudden load changes. Laid in residential or industrial areas, underground or in ducts. If cable gets water inside due to mechanical damage, swellable tapes prevent movement of water inside cable. |
