Copper Clad Aluminium Busbar for New Energy
The copper-clad aluminium (CCA) busbar, also known as a bimetal conductive bar, represents the third generation of energy-saving conductor materials following copper and aluminium. Widely used in power transmission and distribution, it features an aluminium core encased in a copper layer. The CCA busbar offers the combined benefits of both metals, providing high electrical conductivity and reduced weight.
In the new energy industry, combining copper and aluminium is ideal due to copper's excellent thermal conductivity and aluminium's lightweight and cost-effectiveness. This blend enhances heat dissipation and offers design flexibility. Copper ensures efficient heat management, while aluminium reduces overall weight, ideal for weight-sensitive applications. Aluminium's affordability aids cost control, and both metals' good corrosion resistance ensures stability in diverse environments. This strategy balances performance, cost, and lightweight design.
