Iec 60502 Standard Single Core cables
Tus coj nkauj: Plain annealed copper or aluminum conductor.
Conductor Shielding: Conductor shielding consists of a non-metallic, semiconductor composite extruded layer firmly bonded to the insulation layer, excluding all gaps.
Kev rwb thaiv tsev: 1.8/3KV and 3.6/6KV cable ranges are generally insulated with PVC, but also with XLPE, EPR/HEPR.

Daim ntawv thov:
IEC60502 standard power single-core cables are designed for power distribution from 1.8/3KV to 18/30KV at 50Hz. They are mainly used in power supply stations, indoor pipelines, sab nraum zoov, underground and submarine water, zoo li rau lub installation ntawm cables mus rau kev lag luam, distribution stations and power stations.
