Bi-metallic lugs are specially designed to prevent galvanic corrosion when connecting aluminum conductors to copper bus bars in electrical systems. Galvanic corrosion happens when two different metals, like copper and aluminum, touch each other, causing a chemical reaction that can weaken the connection and lead to failures over time. The clever de

In contemporary electrical installations, bi metallic lugs are utilized to provide safe and reliable connections between copper bus bars and aluminum conductors. The connectors are made from an aluminum barrel with a copper palm, which are combined using sophisticated methods such as friction welding. The main reason for employing bi metallic lugs
