Product Introduction
Product Profile
Tinned Copper Insulating Busbar is a high-performance electrical connection material that uses high-purity T2 copper as the base material, and is plated with a uniform tin layer on its surface through an advanced tin plating process. This design not only improves the conductivity and corrosion resistance of the busbar, but also significantly enhances its welding performance and oxidation resistance.
Product technology
Tin-Plated Insulated Bus Bar uses a mature tin plating process, which has the advantages of environmental protection, high efficiency, and uniform plating. The specific process flow is as follows:
Surface treatment
high-temperature electrolytic degreasing, four-level water washing, and activation treatment to ensure that the surface of the copper bar is clean and free of impurities.
Tin plating
Through a six-level tin plating process, a uniform and dense tin layer is formed.
Post-processing
After four-level water washing, hot water immersion, blow-drying and other steps, the stability and durability of the Tinned Copper BusBar's coating are ensured.
Specific application: new energy vehicles
In the power battery system of new energy vehicles, Tinned Copper BusBar is mainly used to connect battery modules to ensure the efficiency and stability of current transmission. Power battery systems need to operate stably under high current loads and require low contact resistance to reduce energy loss and heat generation. The tin layer of the tin-plated busbar has excellent electrical conductivity, its resistivity is low and the conductivity of the oxide is better than that of copper oxide, which can significantly reduce the contact resistance.
In addition, the welding performance of Tin-Plated Insulated Bus Bar is also very good, especially the matte tin plating, which can achieve reliable welding joints and ensure a strong connection between the busbar and the battery module. This welding performance is crucial for the assembly of power battery systems, which need to remain stable in high current and high vibration environments.
The application of Busbar Coating in new energy vehicle power battery systems not only ensures the efficiency and stability of current transmission, but also significantly improves the overall performance and reliability of the system through its oxidation resistance, low contact resistance and corrosion resistance. Choosing tinned busbars as the connection material can effectively reduce energy loss, reduce heat generation, and extend the service life of the battery system.
Differences from ordinary products
Antioxidant
The tin layer forms a strong protective layer to prevent the copper substrate of Tin-Plated Insulated Bus Bar from oxidation and maintain long-term conductive properties.
Welding performance
