4.Application of 11kv power cable
These cables are designed for distribution of electrical power with nominal voltage U0/U ranging from 3.6/6KV to 19/33KV 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.
