IEC 60502 Standard Three Core Cables
Dirigent: Vanlig glödgad koppar- eller aluminiumledare.
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.
Isolering: 1.8/3KV och 3,6/6KV -kabelintervall är vanligtvis isolerade med PVC, but can also be insulated with XLPE, EPR/HEPR.

Ansökan:
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, inomhusledningar, utomhus-, buried and in water, såväl som för installationen av kablar till branschen, distributionsstationer, och kraftverkskablar.
