IEC 60502 Standard Single Core cables
Conductor: Plain annealed mhangura kana aluminium conductor.
Conductor Shielding: Conductor shielding consists of a non-metallic, semiconductor composite extruded layer firmly bonded to the insulation layer, excluding all gaps.
Kusimbisa: 1.8/3KV uye 3.6/6KV tambo tambo dzinowanzoiswa insulated nePVC, but also with XLPE, EPR/HEPR.

Application:
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, panze, underground and submarine water, pamwe chete nekuisa tambo kuindasitiri, distribution stations and power stations.
