| Medium VOLTAGE CABLES |
|
|
| 89/ 154kV XLPE Insulated, Radial and 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 movemnet of water inside the cable. |
