PVC insulated low-voltage power cable is a kind of power cable, which is mainly suitable for transmission and distribution lines with AC rated voltage of 0.6/1kv and below. It is commonly used in urban underground power grid, outgoing line of power station, internal power supply of industrial and mining enterprises and transmission lines under river and sea water. PVC insulated flame retardant power cable is an ordinary power cable, which has flame retardant characteristics and can be used in general special places, such as large buildings, tunnels, petrochemical industry, power stations, mines and other occasions with flame retardant requirements.
