XLPE underground cable ,1 core 35 KV Under ground Power Cable 500 Sq mm

1. Application:

It is used to transmit and distribute power in power transmission and distribution system of 35kV 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. Power cables for power networks, underground, outdoors and in cable

ducting.
