Heavy Duty Long Barrel Copper Tube Terminal are electrical connectors designed for specific applications where longer barrels are required to accommodate wires. These lugs are typically used with smaller wire sizes and lower current-carrying capacities compared to heavy-duty lugs. These lugs have a tubular or cylindrical shape, similar to other tube lugs, but they feature longer barrels. The extended barrel length allows them to accommodate longer sections of wire, making them suitable for specific wiring configurations. Heavy Duty Long Barrel Copper Tube Terminal are typically made from high-conductivity copper materials, such as electrolytic copper or high-purity copper, to ensure good electrical conductivity and corrosion resistance.
