Cables IEC 60502-2 in copper or aluminium


International :  IEC 60502-2



IEC 60502-2 cables are for public power distribution network 18/30 kV.


The cable is made of armoured or not armoured 1 core or 3 cores.


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


All drum types, lagged or not, up to a diameter of 3.40 m and a total weight of 12 t.
