Continuous tinning technology for copper busbars refers to the process of continuously coating a layer of tin on the surface of the copper busbar. After continuous tinning, the copper busbar can greatly improve its surface corrosion resistance, weldability, plasticity and mechanical strength, which well protects the surface of the copper busbar and increases its service life.

I. What is the continuous tinning technology of copper busbars?
The continuous tinning technology of copper busbars refers to the process of continuously coating a layer of tin on the surface of copper busbars. After continuous tinning, the copper busbars can greatly improve their surface corrosion resistance, weldability, plasticity and mechanical strength, which well protects the surface of the copper busbars and increases their service life.
II. What is the role of continuous tinning of copper busbars?
1. Improve corrosion resistance
A small part of copper will form some unstable oxide films, which will affect its antioxidant ability and easily lead to corrosion and shortened life of copper busbars. However, through the continuous tinning treatment of copper busbars, a dense and compact tin layer can be formed, forming a protective layer on the coating surface, effectively isolating the contact between copper and air, preventing copper wires from producing oxidation reactions, improving the antioxidant performance of copper busbars and extending their service life.
2. Improve weldability
After the continuous tinning treatment of copper busbars, the tin layer on its surface can improve the weldability of copper busbars, making the welding process more stable and reliable, and reducing the risk of brittle fracture during welding.
3. Improve plasticity
After continuous tin plating, the tin layer on the surface of the copper busbar can form a small and dense grain structure, which can better protect the copper surface, improve the plasticity of the copper busbar, reduce the processing strength, and make the copper busbar interface more precise.
4. Improve mechanical strength
After continuous tin plating, the surface tin layer of the copper busbar plays a role in protecting the copper, enhancing the mechanical strength of the copper busbar and extending the life of the copper busbar.
In short, the continuous tin plating technology of copper busbar is a surface treatment technology that is gradually being widely used. It can greatly improve the corrosion resistance, weldability, plasticity and mechanical strength of the copper busbar, and can effectively extend the service life of the copper busbar.
