| Copper clad aluminum busbar is bimetal conductor developed to provide an economic and alternative to solid copper. CCA busbar is produced by hydrostatic extrusion process, and consist of solid core of electrical grade aluminum with a pressure bonded outer layer of high conductivity copper. |

 |
CCA busbar therefore offers economic and weight saving advantages over solid copper, while retaining the surface properties of a copper busbar. It is often possible to substitute a copper bar with a CCA busbar of equal dimensions. This yields the maximum cost saving.
All rectangular and round sections are produced using a nominal copper cladding of 15% by volume (37% by weight) with the exception of certain sizes of high aspect ratio which are produced with nominally 20% copper by volume (45% by weight). |

■ Good conductivity AC current carrying capacity is 81%-85%.
■ Low weight CCA busbar density is only 37%-45% of solid copper busbar,so the length of cca
busbar is 2.5-2.7 times of solid copper bar. Reduce weight by up to 60%.
■ Good mechanical property Excellent tensile strength, flexibility and extensibility. It can be
punched,sheared and ended easily. In order to improve its anti-corrosion property, tin or zine
can be coated on the surface of cca busbar
■ Save cost CCA busbar can save as much as 40% compared with a copper bar of equal |

Good conductivity: AC current capacity of copper clad aluminum busbar which copper volume ratio is 15% is 85% of pure copper busbar.
Low weight: Density is only 37%-40% of pure copper busbar. In other words, CCAbusbar length is 2.5-2.7times of pure copper busbar in the same weight.
Good mechanical property: There have good tensile strength and flexibility and extensibility and firm metallurgy bonding.
Good extensity and productivity: It can be punched and sheared and bended. In order to improve anti-corrosion property, tin or zinc can be coated on the surface of copper.
Best choice: Save cost and environment –friendly and free of any pollution. |

CCA busbar has been approved for use in equipment by many authorities, including the following:
Germanischer Lloyd; Det Norske Veritas; ABS; Bureau Veritas; Lloyds Register of Shipping: SABS; ULA; National Power Supply Company; National Grid Company; electrical and water utilities.
CCA busbar?complies with BS 159:1957, and conforms to DIN 43670 Part2. The aluminium core is of electrical grade and the copper cladding is to BS 2871/C101.
CCA busbar has been successfully tested for short circuit performance in many applications by authorities such as: ASTA (The Association of Short Circuit Testing Authorities); KEMA (NV tot van Elektrotechnische Materialen); Electrisches Prüfamt, München. |

Dalian sinocca technology Co.,Ltd is established in 2003, which most of engineers engaged in bimetal material researching and producing since 1999. As a manufacturer, we produce main products including copper clad aluminum busbar, copper clad aluminum flat wire, zine or tin coated cca busbar and so on.At present, there have 14 patents and Intellectual Property Rights for cca industry in sinocca company.
As copper clad aluminum busbar inventor and designer in china, Dr yunzhong wu, who is dedicated to bimetal industry researching longterm. He develop hytrostatic extrusion technology for producing cca busbar. the hydrostatic extrusion process uses a fluid compression medium under very high pressure to force material through a precision made die. |
