Bi-metallic lugs are electrical connectors designed to provide a reliable and durable connection between two dissimilar metals, typically aluminum and copper. These lugs are constructed using a combination of materials, with the main body typically made of aluminum and a layer of copper or copper alloy coating on the contact surface. The use of bi-metallic lugs is common in electrical applications where aluminum cables need to be connected to copper components or vice versa. This is important because connecting aluminum and copper directly can lead to galvanic corrosion due to the difference in their electrical properties. Bi-metallic lugs help prevent this corrosion by providing a barrier between the two metals. Bi-metallic lugs are available in various sizes and configurations to accommodate different cable sizes and types. They are commonly used in electrical distribution systems, industrial equipment, and other applications where reliable electrical connections between dissimilar metals are required. These lugs are known for their durability, excellent electrical conductivity, and resistance to corrosion, making them a preferred choice for various electrical installations.
