1. Application
It is used to transmit and distribute power in power transmission and distribution system of 6～35kV. It is generally applied to the fields including power, construction, mines,metallurgy, petrochemical industry and communications. And it is used as replacement of oil-immersed paper insulated power cable and partially as replacement of PVC insulated power cable.
