Copper clad aluminum bus-bar
CCA busbar therefore offers economic and weight saving advantages over solid copper, while retaining the surface properties of a copper busbar. It is often possible to substitute a copper bar with a CCA busbar of equal dimensions. This yields the maximum cost saving.
All rectangular and round sections are produced using a nominal copper cladding of 15% by volume (37% by weight) with the exception of certain sizes of high aspect ratio which are produced with nominally 20% copper by volume (45% by weight).
Advantage
- Good conductivity AC current carrying capacity is 81%-85%.
- Low weight CCA busbar density is only 37%-45% of solid copper busbar,so the length of cca busbar is 2.5-2.7 times of solid copper bar. Reduce weight by up to 60%.
- Good mechanical property Excellent tensile strength, flexibility and extensibility. It can be punched,sheared and ended easily. In order to improve its anti-corrosion property, tin or zine can be coated on the surface of cca busbar
- Save cost CCA busbar can save as much as 40% compared with a copper bar of equal
Application
