The main function of conductive pole is to transmit current from power supply to load, to ensure the stable operation of power system. Its design and structure are different according to specific application, including different shapes and sizes, to meet different current carrying capacity and mechanical strength requirements. The surface of conductive pole is usually treated to reduce resistance and improve conductivity. In electrical equipment, conductive pole is often used to connect circuit, transmit large current or high voltage, and ensure the reliability and safety of connection. Its performance directly affects the efficiency and life of equipment, so the quality of material and processing technology need to be strictly controlled in design and manufacture.
