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

Applicazione:
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, conduiti interni, all'aperto, buried and in water, In quantu à l'installazione di i cables à l'industria, Stazioni di Distribuzione, è CABLE DI SALITÀ POWER.
