The TLMY series energy-saving copper clad aluminum transition busbar researched and developed by Henan Signi Aluminum Co., Ltd. has successfully developed its own intellectual property rights TLMY series based on the advanced technology of similar products abroad and the characteristics of distribution conductor materials in China's electrical industry. Energy-saving CCA flat busbar. The product uses a unique bimetal composite material processing technology, through a variety of plastic deformation and heat treatment process, the copper layer is simultaneously and uniformly coated on the aluminum conductor material, thereby achieving metallurgical bonding between two different melting point metal atoms. A copper-aluminum bimetallic conductor material is formed in a unitary cross section.



Technical characteristics of Bimetallic bimetal busbar:
Good electrical conductivity: copper clad aluminum CCA flat busbar with a copper layer volume ratio of 18%-22%
The flat copper wire has an alternating current carrying capacity of 85 to 93% of the flat copper wire.
Light weight: The density of CCA busbar is only 39~42% of flat copper wire, and the weight of copper clad aluminum flat busbar of the same length (volume) is 1/2.5~2.7 of flat copper wire.
Strong copper-aluminum bonding: permanent interatomic bonding between two different metallic materials, and uniform distribution of copper layers without any physical defects.
Good mechanical properties: good tensile strength, bendability and elongation.
Good ductility and reliability: After special heat treatment process, it has certain plasticity, which is beneficial to shearing, bending and winding. In order to ensure the reliability of the product, it is also possible to wrap the insulating material on the surface.
Cost savings: saving copper, aluminum to copper, greatly reducing production costs (can be reduced by more than 50%). According to the national power industry standards, the specifications are complete and convenient to choose.
Second, the product application range
The copper clad aluminum flat busbar product has a wide range of applications and can be used as a substitute for flat copper wire for the winding of electrical equipment such as large motors, reactors, inverters, varistors, electric welders, dry (oil-immersed) transformers, and lighting busbars. row. It is the best choice for enterprises to reduce costs, save copper and reduce production liquidity.
