Product Details

21/35kv MV Insulted Power Cables Three Cores Cables to IEC 60502 Standards:
IEC 60502 Part 2(3.6/6KV to 18/30KV)

21/35kv MV Insulted Power Cables Three Cores Cables to IEC 60502 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.

21/35kv MV Insulted Power Cables Three Cores Cables to IEC 60502 Construction:

Conductor: Plain annealed copper or aluminium complying with IEC 60228 class 2.
Conductor Screen: extruded layer of semi-conducting crosslink compound
Insulation: Insulation is of polyvinyl chloride (PVC) intended for 1.8/3.6KV and 3.6/6KV cables, cross-linked polyethylene compound (XLPE)
