Selecting the right surface treatment for copper busbars is vital in high-temperature environments. Nickel plating, with superior resistance to heat, oxidation, and corrosion, is ideal for high-voltage substations and switchgear. Tin plating offers excellent conductivity and corrosion protection for medium- to low-temperature applications but may oxidize or fail under prolonged heat. The choice should align with temperature and application needs.
