As a leading bimetal manufacturer in the world, Sinocca Technology (Dalian) Co., Ltd. is specialized in producing copper clad aluminum busbar, (CCA) flat wire, tin or zinc plated copper clad aluminum busbar. The CCA busbar can replace the copper busbar. Cost saving is 60%.

CCA busbar can be applied in HV/ MV/LV distributor, switchboards, motor control centers, panel boards, busbar chambers, busbar trunking systems, rectifiers motor windings, fuse gear, crane rail supply systems, vacuum switchgear, generator set, transformer substations, railway traction equipment, bimetal conductors in aluminum foil wound transformers, railway applications, etc.

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 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.
