12/20kv Cu (AL) / XLPE /Copper Tape Screen / Swa (STA) / PVC Power Cable

APPLICATIONS:

The cables are designed for distribution of electrical power with nominal voltage Uo/U 19/33KV and frequency 50Hz. It is used to transmit and distribute power in power transmission and distribution system of 33kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable.

STANDARD:

BS 6622

BS 7835 (LSZH Version)

CONSTRUCTION:

Conductor: Plain annealed copper or aluminium complying with IEC 60228/BS 6360. Copper

conductors shall be stranded and aluminium conductors shall be either solid or

stranded.

Conductor Screen: Extruded layer of semi-conducting cross-linkable compound is applied

over the conductor and shall cover the surface completely. The minimum thickness is 0.3mm
