A Heavy Duty Copper Lugs is an electrical connector designed for heavy-duty and high-current applications. Lugs are used to terminate and secure copper wires or cables to various electrical equipment, such as circuit breakers, switches, transformers, or other electrical components. They are typically made from high-conductivity copper materials, such as electrolytic copper or high-purity copper. These lugs are designed with a tubular or cylindrical shape, and they often feature a flared or bell mouth to facilitate easier insertion of thick copper wires or cables. Heavy Duty Copper Lugs is known for good heat resistance properties, which makes them suitable for applications where electrical currents generate heat.
