TSLF 72 kV 1x400A

Description

Description

Standards

  • International
    IEC 60840

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.

Meter marks

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

Usage: Indoor, Underground, Outdoors

Intended for high voltage energy distribution

Fire properties:

Halogenfree
Cable marking:

NEXANS NS TSLF  kV 1 x mm²/mm² MONTH YEAR, metermarks
