TSLF-O 24kV 1x400A

Description

Description

Standards

  • International
    HD 620.10K; IEC 60502-2

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.

Screen section: Value given is the physical cross section of the copper wires in one core.

The cable has three tubes for future installation of optical cables.

Usage:

Indoor

Underground

Outdoors

Intended for high voltage energy distribution

Fire properties:

Halogen free

Cable marking:

NEXANS NS TSLF XX kV 1 x mm²/mm² MONTH YEAR

Lifemark
