BI-Metallic Barrel Lugs

BI-METALLIC BARREL LUGS are precision-engineered to provide a safe and durable solution for connecting aluminum conductors to copper busbars, terminals, or cables. The design features a friction-welded barrel made of high-conductivity aluminum and electrolytic copper palm, ensuring superior electrical performance while minimizing the risk of galvanic corrosion. This construction makes them ideal for high-power applications where dissimilar metals need to be joined securely.

Built to meet international electrical standards, these lugs are manufactured with a smooth barrel interior for optimal crimping and reduced contact resistance. The copper palm is tin-plated for maximum corrosion resistance and long service life, while the aluminum barrel is pre-filled with an oxide-inhibiting compound to prevent oxidation and enhance conductivity. The robust structure guarantees mechanical strength, making them suitable for demanding installations in switchgear, transformers, control panels, and industrial power systems.

Available in a wide range of sizes, BI-METALLIC BARREL LUGS support conductor sizes from 10 mm² up to 630 mm², with a barrel length designed to provide maximum crimping flexibility. They are rated for operating voltages up to 36 kV, with temperature resistance from -55°C to +90°C, ensuring reliable performance even in harsh environments. These lugs offer an efficient, long-lasting connection solution for electrical engineers and technicians looking for safe and high-quality termination components.
