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