Description
MV cables IEC 60502-2 in copper or aluminium
Standards
International : IEC 60502-2Description
Usage
IEC 60502-2 cables are for public power distribution network 18/30 kV.
Design
The cable is made of armoured or not armoured 1 core or 3 cores.
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 3.40 m and a total weight of 12 t.
