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.

The application of copper busbar connectors in high-voltage cabinets mainly involves transporting current and connecting electrical equipment. According to the processing technology and types of copper busbars, they can be divided into brass, purple copper, electroplated tin copper busbars, etc. Among them, copper has excellent conductivity and strong corrosion resistance, making it widely used in high-voltage cabinets.

Copper busbar connector has good convenience in tapping and is more convenient to use: plug-in busbar trunking can connect the power supply of the main line to the branch line through plugging. Simply insert the plug into the busbar trunking to complete the connection, without the need for customized cables, improving construction efficiency.
