18/30kv MV Power Cables Single Cores Cables Standards
IEC 60502 Part 2(3.6/6KV to 18/30KV)

18/30kv MV Power Cables Single Cores Cables 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.

18/30kv MV Power Cables Single Cores Cables Construction

Conductor: Plain annealed copper or aluminium complying with IEC 60228 class 1 or 2.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting compound applied on top of a semi-conducting tape.
Insulation: XLPE
