Copper will oxidize in the air, producing copper rust and affecting its conductivity. In order to avoid copper oxidation, tin plating can be applied to the surface of copper conductive tapes. In fact, gold or silver plating can also be used to improve conductivity, but the cost is higher. Therefore, many customers choose tin plating to save costs.

The high-voltage copper busbar of new energy vehicles is used for the transmission of high-voltage electrical energy to ensure safe and reliable electrical connections. The high-voltage copper busbar plays an important role in the transmission of electrical energy. The selection of wire cross-sectional area and material plays a crucial role in the performance of high-voltage wiring harnesses.

Copper braided tape and copper stranded wire are both conductive materials made of copper, but they have some differences in structure and application. The following are the main differences between them:

Copper tin plating process usually has two methods: hot tin plating and electroplating tin plating. Tin plating can not only increase the corrosion resistance and oxidation resistance of copper busbar connectors, but also improve their conductivity and thermal conductivity. However, due to various factors, the surface of copper busbars is prone to blackening after tin plating.
