IEC 60502 Standard Three Core Cables
Conductor: Conductor ya wazi ya shaba au aluminium.
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 na 3.6/6KV safu za cable kwa ujumla zimewekwa maboksi na PVC, but can also be insulated with XLPE, EPR/HEPR.

Maombi:
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, Njia za ndani, nje, buried and in water, na pia kwa usanidi wa nyaya kwenye tasnia, Vituo vya usambazaji, na nyaya za kituo cha nguvu.
