Copper Clad Aluminum Busbar (CCA Busbar)
Request a Quote
CCA busbar is copper clad aluminum busbar consisting of a solid core of electrical grade aluminum and an outer layer of high conductivity copper, which is manufactured through unique pressure bonding process. CCA busbar offers advantages of lightweight and low cost while remaining surface properties of copper busbar, this makes the CCA busbar an economical alternative to pure copper busbar.
Huawang can provide CCA busbar with a wide option of cross sectional areas to fit your specific needs.
Applications
- High and low voltage distribution switchgear busbar (copper clad aluminum busbar)
- High and low voltage busbar, combiner busbar, conductor rail (copper clad aluminum busbar)
- Transformer windings and reactor windings (copper clad aluminum flat wire)
- Various types of copper aluminum bimetallic connector
