8.7/15Kv Single Core Cables according to IEC 60502

8.7/15Kv Single Core Cables according to IEC 60502

basic information
Detail
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,
 
Standards
IEC 60502 
 
Construction
Conductor: Plain annealed copper or aluminum complying with IEC 60228 class 1 or 2, 
Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting compound firmly bonded to the insulation to exclude all air voids, The conductor screen is not necessary for both PVC and EPR/HEPR insulated 1,8/3KV and 3,6/6KV cables,
Insulation: Insulation is of polyvinyl chloride (PVC) intended for 1,8/3KV and 3,6/6KV cables, cross-linked polyethylene compound (XLPE) or ethylene propylene rubber (EPR/HEPR),
 
Single core 8,7/15KV (Um=17,5KV)
