IEC 60502 Standard Three Core Cables
Direktoro: Ebena recozita kupro aŭ aluminio-konduktilo.
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.
Izolaĵo: 1.8/3KV kaj 3.6/6KV kablo gamoj estas ĝenerale izolitaj kun PVC, but can also be insulated with XLPE, EPR/HEPR.

Apliko:
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, indoor conduits, subĉiela, buried and in water, same kiel por la instalado de kabloj al la industrio, distribution stations, and power station cables.
