IEC 60502 Standard Three Core Cables
Stiùiriche: Plain annealed copper or aluminum conductor.
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.
Insulation: 1.8/3KV and 3.6/6KV cable ranges are generally insulated with PVC, but can also be insulated with XLPE, EPR/HEPR.

Iarrtas:
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, Bidh a-staigh a 'dèanamh, a-muigh, buried and in water, A bharrachd air airson càballan a chuir chun ghnìomhachas, Stèiseanan Sgaoilte, agus càbaill stèisean cumhachd.
