CEI 60502 Standard Three Core Cables
Conductor: Conductor de cobre o aluminio recocido liso.
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.
Aislamiento: 1.8/3Las gamas de cables KV y 3,6/6KV generalmente están aisladas con PVC., but can also be insulated with XLPE, EPR/HEPR.

Solicitud:
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, conductos interiores, exterior, buried and in water, así como para la instalación de cables a la industria, distribution stations, and power station cables.
