YJLV cable full name crosslinked polyethylene insulated polyvinyl chloride sheathed aluminum core power cable

VLV cable full name PVC insulated PVC sheathed aluminum core power cable

Due to the excellent conductivity of copper conductor, more and more projects use copper core power cable as the main road of power supply system, while the application of aluminum core power cable is less, especially in the power system with higher voltage, the choice of copper core cable is more.
