The copper clad aluminum busbar is a composite conductive material whose outer layer is copper and the inner core is aluminum.It is widely used in electric control power distribution equipment. As a high current current carrying conductor, it is designed to replace copper busbars and is easy to process and use like copper busbars.
According to the "skin effect" principle, the current is concentrated on the surface of the conductor, so the copper of the inner core of the pure copper busbar does not play a large role.The copper clad aluminum busbar is based on this principle to replace the copper inside the copper row with aluminum, which is combined into a copper clad aluminum conductive material through a series of complicated processes.
The copper clad aluminum busbar makes full use of the characteristics of strong corrosion resistance, low contact resistance, and large current carrying capacity of the copper busbar. It also has the advantages of light weight and low cost of the aluminum busbar.The advantages of copper and aluminum are fully utilized, and their respective shortcomings are overcome. At the same time, they have been widely used in the electrical control and distribution equipment industry. It can save 40-50% of the conductor costs for customers.
The main application areas of copper clad aluminum bus bars are: high-frequency, intermediate-frequency heating equipment, combined battery connections, railway tracks and other conductors, crane sliding contact wires; busway systems, busbar high-voltage, low-voltage busway; switch cabinets (low-voltage, medium- Pressure, high voltage), switchboard, electric control box.
