User benefits:
Diffusion free high voltage cable. Avoids therefore growth of water trees in the XLPE insulation which increases the lifetime.
The semiconducting layer makes it easy to test the outer sheats integrity while on drum, before backfilling, in plastic tubes etc.
The cable has one tube witch includes an optical fiber cable, and one ground wire.
Usage:
Indoor
Underground
Outdoors
Intended for high voltage energy distribution
Fire properties:
Halogen free
