STANDARD : BS7835
Conductor : Plain annealed copper or aluminium
Insulation : Cross-linked Polyethylene Compound XLPE Or EPR
Voltage : 3.8/6.6KV to 19/33KV
APPLICATIONS
The single core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 3.8/6.6KV 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.
Conductor
Plain annealed copper or aluminium complying with IEC 60228/BS 6360. Copper conductors shall be stranded (class 2) and aluminium conductors shall be either solid or stranded (class 2).
Insulation
Insulation is of cross-linked polyethylene compound XLPE (GP8) conforming to BS 7655-1.3 or EPR (GP7), conforming to BS 7655-1.2.
