Медно облечен алуминиев проводник

The copper-clad aluminum conductor is a composite conductor with an aluminum busbar core, where high-quality copper strips are concentrically and firmly wrapped around the aluminum busbar surface through advanced cladding welding technology. This process achieves atomic-level metallurgical bonding between the copper layer and aluminum core, integrating the two metals into an inseparable whole. Such a unique structure endows the conductor with the low-density and cost advantages of aluminum, as well as the excellent electrical conductivity of copper.In terms of cost, tin-plated copper-clad aluminum conductors can significantly reduce raw material costs. Regarding electrical performance, based on the "skin effect", high-frequency current mainly transmits on the conductor surface. The copper layer of the copper-clad aluminum conductor is precisely located on the outer layer, enabling it to effectively carry current and ensure excellent conductivity. Additionally, the tin-plated layer on the conductor surface acts as a corrosion-resistant protective coating, significantly enhancing oxidation and corrosion resistance to adapt to various complex среди .
