Bi-metallic lugs are crucial for electrical connections between copper and aluminum conductors. Friction welding is used to provide a secure and reliable connection between the copper palm and aluminum barrel of bi-metallic lugs. Without bi-metallic lugs, a copper to aluminum contact will experience galvanic corrosion, causing the connection to gradually lose its integrity and develop electrical resistance. Industries will be able to have lengthy, solid electrical contacts by using bi-metallic lugs, which will reduce the risk of overheating and power outages.
Galvanic corrosion is felt when there are two various metals, such as copper and aluminum, making contact with each other under conditions of an electrolyte, say moisture or humid air. Upon contact, aluminum corrodes at a high speed, causing the conductivity to decrease and electrical risk. Bi-metallic lugs solve this challenge by offering a secure transition of the two metals, avoiding any direct contact and the possibility of corrosion. Also, proper utilization of the lugs improves conductivity, reduces the need for maintenance, and enhances system efficiency to the maximum level, hence a necessity in power distribution systems, industrial systems, and renewable systems.

For use in applications requiring secure electrical contacts, Pioneer Powers offers high-performance anti-galvanic corrosion and enhanced performance bi-metallic lugs. Their highly engineered lugs offer hardness, conductivity, and safety even in extreme conditions. Spending on bi-metallic lugs saves the life of electrical systems as well as maintenance costs, hence constituting a smart investment in modern electrical installations.
