Copper clad aluminum bus bar

Copper clad aluminum bus bar

Copper clad aluminum is also called copper clad aluminum busbar, Copper (CCA) clad aluminium bus-bars. Copper clad aluminum bus bar is a kind of high-tech energy-saving conductor materials, also have the characteristics of conductive copper and  small density of aluminum.



As early as 1960s, some European and American countries began the research and application of copper clad aluminum materials, and the development of conductor standard. Copper in Europe is called following after the third generation of copper and aluminum conductor, all countries have the relevant industry standards, has entered the practical stage, widely used in metallurgy, automation, high and low voltage electrical appliances, construction industry and metallurgy industry etc..

Copper clad aluminum busbar

Copper clad aluminum busbar is a kind of aluminum matrix coated with copper, permanent metallurgical bonding between the two metal atoms, so they formed between the surface light, round, no defects. It is a new type of conductor material which combines the high quality, stable and conductive properties of copper with aluminum's low cost energy and combines low contact resistance. Can fully replace pure copper, copper accounted for 40%, accounting for 60% of the proportion of aluminum, the same specification case is pure copper 2 - 2.5 times as long, load flow is 85% pure copper, when the choice section area can fully reach the same load with the copper flow around 10%, the mechanical properties and electrical properties are to meet customer requirements.

Advantage of copper clad aluminum bus bar:

1. Good conductivity, copper volume ratio of 15% or 20% of the electrical properties of copper clad aluminum and copper, compared to its AC load flow is pure copper 85%.

2. Light weight: copper coated aluminum density is only pure copper 37%-40%, the length of the same weight (volume) of pure copper is 2 - 2.5 times.

3. Good mechanical properties: good tensile strength, flexibility and elongation.

4. Solid copper binding: two atom crystal between different metal materials in a variety of environmental temperature to achieve permanent combination, and the copper layer (layer of tin, zinc) distribution, there is not any physical defect.

5. Good ductility and reliability: after a special heat treatment process, has a certain plasticity, is conducive to punching, cutting and bending processing, products are not cracking, not separation. In order to improve the corrosion resistance, tin coating and zinc plating can be applied on the surface of copper layer.
 
6.The best choice: save copper, greatly reduce production costs, green environmental protection, without any pollution.
 
Note: according to user processing of various width and thickness of the copper clad aluminum busbar.
 
Copper clad aluminum, for replacing copper, aluminum row. Widely used in. Automation, metallurgy, high and low voltage electrical equipment, construction industry and metallurgical industry. The product adopts advanced foreign double metal composite technology, stable quality, reliable performance, is a high-tech energy-saving products.
