IEC 60502 Standard Three Core Cables
Revisora: Conductor simple de coure o alumini recuit.
Conductor shielding: The conductor shielding shall be non-metallic and shall consist of an extruded semi-conductive compound with a semiconductor strip applied on top of the semiconductor compound. The conductor shield is not required for PVC, EPR/HEPR insulated cables in the 1.8/3KV to 3.6/6KV range.
Aïllament: 1.8/3Les gammes de cables KV i 3,6/6KV estan generalment aïllades amb PVC, but can also be insulated with XLPE, EPR/HEPR.

Aplicació:
Three-core cables are designed for power distribution from 3.6/6.6KV to 19/33KV at 50Hz. They are mainly used in a wide range of applications such as power supply stations, conductes interiors, exterior, buried and in water, així com per a la instal·lació de cables a la indústria, estacions de distribució, i cables de centrals elèctriques.
