IEC 60502-2 / NF C 33-220 18/30 (36) kV

Description

Description

Standards

  • International
    IEC 60502-2
  • National
    NF C33-220; NF C33-220

Usage

IEC 60502-2 or NF C 33-220 cables are for public power distribution network 18/30 kV.

Design

The cable is made of not armoured 1 core. A semi-conductive tape is layed beneath copper screen.

 

Insulation

The polyethylene cross-linking process ensures:

  • Excellent heat resistance (90 °C)
  • Good mechanical strength
  • Excellent behaviour under short circuit conditions (250 °C)
  • Extremely good resistance to low temperatures

Drumming

All drum types, lagged or not, up to a diameter of 3.00 m and a total weight of 12 t.
