Purpose of copper busbar surface treatment:

1. To prevent corrosion of copper busbars by the external environment, the measures include: nickel plating, zinc plating, tin plating, silver plating, painting, and using protective sleeves, etc.

2. Improve insulation performance and prevent contact with live parts. Measures taken include: applying insulated sleeves (cold/hot shrink insulation sleeves) and applying joint sleeves.

3. Increase conductivity: Copper is used for conducting electricity. The order of conductivity strength is: gold, silver, copper, aluminum.... Because alternating current passes through, most of the current flows on the surface. If the copper body is not plated with gold or silver, it is not plated. So why plate with tin or nickel? The main reason is corrosion protection. Therefore, under a permanently allowed environment, nothing is plated, except for gold and silver. After plating, the conductivity decreases.

4. Enhance heat dissipation performance, mainly by applying black paint.
