Copper clad aluminum(CCA) busbar bus bar

Jan 17, 2023

The clad aluminum busbar bus bar produced by has solved the two difficult problems of copper-aluminium compound which is easy to oxidize and cut oxide film and difficult to eliminate the intermetallic compound (Al2Cu) between dissimilar copper and aluminium at lower temperature. SEM analysis shows that the thickness of transition layer between copper and aluminum in traditional copper-clad aluminum bars is 15-50um, while the thickness of transition layer between copper and aluminum in our company is only 1-2um, which is far lower than that of traditional copper-clad aluminum bus bar. The problem can save more than 30% of the cost when used.

The copper clad aluminum busbar bus bar produced by is suitable for busbar and switchgear industry. The product has excellent comprehensive performance and can meet the requirements of industry: bending, punching, drilling, surface treatment and so on.

It is suitable for high and low voltage switchgear, busbars, switchgear, electrical appliances, electrolyzer and so on.

Product features: low density and low comprehensive cost, which is a cost-effective solution for enterprises.
