Copper Clad Aluminum Busbar

Copper Clad Aluminum Busbar, also called CCA busbar and bimetal conductive bar, is the third - generation "new energy - saving conductor material" after copper and aluminum. It's widely used in power transmission and distribution systems. With an aluminum core wrapped in a copper layer, it combines copper's high conductivity and aluminum's low weight.​
This structure gives it great performance. The outer copper layer ensures efficient current flow, while the inner aluminum core reduces weight. So, it's ideal for applications needing both good electrical performance and lightness, like in high - rise buildings and power plants. Moreover, compared to pure copper busbars, it's more cost - effective as aluminum is cheaper and more abundant.
