Specifications

CCA busbar: good conductivity, light weight, excellent mechanical property, strong bonding between copper and aluminum.

Copper Clad Aluminum Busbar/CCA busbar

Our company use instaneous combination technology to manufature CCA busbar. 

advantages of copper clad aluminum busbar

1. Good conductivity:  Compared with the electrical property of pure copper busbar, AC carring capacity of 15%-20% copper volume copper clad aluminum busbar is more than 85% of the red copper busbar.

2. light weight:  The density of the cca busbar is 37%-40% of the pure copper busbar, the lenght is 2.5-2.6 times compared with pure copper busbar in the condition of same weight. The weight ratio between pure copper busbar and bimetallic copper busbar is 2.6:1.

3. Good mechanical property:  Good ductility, CCA busbar do not exist wrinkle,bubble or surface crack in the process of bending. operational performance of the product can be assured.

4. strong bonding between copper and aluminum:  Two different metallic material reach permanently atom bonding in the specific environmental temperature. Do not exist any physical defects.

5. Good extensibility and reliability: It has plasticity through special heating process technology and be beneficial to punching, shear, bend process. Tining,Zincing and silver coating process to ensure corrosion resistance.

6.  Best selectivity:  Save copper resource to reduce  production and matching cost. It has no contamination, it is environmnetal friendly.Our company can manufacture various specification copper clad aluminum busbar. We have superier production equipment to fulfil technology and industry requirement  completely.
