Description

Description

Standards

  • Product
    HD 620.10K

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

Cable marking:
