Copper and Alumium Bar is a large current conductive products, it could be use in low and high voltage electric appliance, contact terminal, distribution system bus duct and other electrical engineering, it is also widely used in extra high current electrolytic smelting engineering such as metal smelting, electrochemical, electroplate, chemical caustic soda
Copper, aluminum bars all have good conductive properties, which are widely used in power transmission and distribution, power & electronics, and electric car field. Moreover they also have good mechanical properties, which are different from other kinds of conductive connector. Therefore they can also be used as structure units.
