User benefits:
Diffusion free high voltage cable.
Avoids growth of watertrees in the XLPE insulation and increases the lifetime of the cable.
Sheath integrity may be tested while on drum, before backfilling, in plastic pipes etc.
Screen section: Value given is the physical cross section of the copper wires in the screen of one core.
Usage:
Indoor
Underground
Outdoors
Intended for high voltage energy distribution
Fire propertirs:
Halogen free
