Copper clad aluminum bus bar

详情

Copper Clad Aluminum busbar (CCA busbar) is a kind of busbar with flatted cross section and produced by applying unique manufacture technology for bimetallic composite material, by means of multiple plastic deformation and heat treatment process. According to dimension of cross section area ,CCA busbar is divided into two type: the one with cross section area less than 11*3.6 named as CCA flat wire, contrary, the other one is named as CCA busbar.

Features:
Good conductivity: Current capacity of CCA busbar with 17% copper volume is 85% of pure copper busbar.
Light Weight: Density of CCA busbar is 38%~42% of the of copper busbar; With same size and weight, length of CCA busbar is 2.3~2.5times of that of copper busbar.
Good Mechanical Characteristics: Good tensile strength, bendability and extensibility
Close bonding: Metallurgical bonding between copper and aluminum and uniform copper thickness.
Good extensibility and reliability:
After special heat treatment process, CCA busbar has good plasticity which is good for further process such as punching, shearing, bending and so on.In order to improve CCA busbars anti-corrosion property, tin plating, nickel plating and galvanized process can be done.
Economic performance: With the same current capacity and length, the cost of copper clad aluminum busbar can be reduced 30%~40%,compared with pure copper busbar.
Application:
High Frequency/Middle Frequency Heating Device; Combined Accumulator Connector; Crane Trolley wire;  Bus duct System; Busbars; Low Voltage Bus duct; Switch Cabinet ; Switch Board;Electric Cabinet;
