What is the purpose of conductor plating?

The purpose of conductor plating is primarily to prevent corrosion. When conductors are exposed to environmental elements, such as moisture and pollutants, they can oxidize or corrode over time. This corrosion can lead to increased resistance, reduced conductivity, and potential failure of electrical connections. By applying a protective layer, typically made of metals like gold, silver, or tin, the underlying conductor is safeguarded against these harmful effects.

Although enhancements in conductivity, weight reduction, or increased flexibility might play roles in conductor design and materials selection, the primary and most crucial function of plating is the protection against corrosion, ensuring long-term reliability and performance in various applications, especially in aviation where safety is paramount.
