Bi-metallic lugs are required to produce reliable electrical connections between copper and aluminum conductors for effective transmission of power. The lugs underpinning these conductors are frequently exposed to temperature variations in factory and outdoor conditions, resulting in thermal expansion and contraction. Aluminum and copper possess varying rates of expansion, with alternation of temperatures for repeated cycles causing loosening of connection, increased resistance, and risk of overheating. Ultimately, this leads to deterioration of the connection, making the entire electrical system less reliable.

To avoid thermal degradation, the use of high-quality bi-metallic lugs with suitable coatings, e.g., tin plating, can prevent oxidation and preserve conductivity. Application of compression or crimping methods that form a strong mechanical bond reduces the effect of expansion and contraction. The use of anti-oxidation compounds and regular inspection of connections can also identify and resolve early wear patterns. In hot environments, the application of heat-resistant insulating materials at the points of connection can also enhance the lifespan of bi-metallic lugs.

For applications in extreme temperature conditions, Pioneer Powers offers robust and corrosion-resistant bi-metallic lugs capable of withstanding severe thermal cycles. Through the selection of suitable materials, proper installation practices, and periodic maintenance, companies can maximize the lifespan of their electrical connections and avoid temperature-related failures. With these practices in place, stable and efficient power distribution is ensured even in challenging environments.
