36KV Copper aluminum power electric XLPE insulated high-voltage power cable Standards
IEC 60502-2
36KV Copper aluminum power electric XLPE insulated high-voltage power cable Application
The single core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 1.8/3KV to 26/35KV and frequency 50Hz. They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.
