Precision-machined from 99.9% high-purity electrolytic tough pitch (ETP) copper, this crimp lug provides exceptional current-carrying capacity in low to medium-voltage systems. Compliant with UL 486B and IEC 61238-1 standards, it supports conductor cross-sections from 10 mm² to 630 mm² in systems operating up to 10 kV. Its solid copper construction eliminates potential failure points found in plated or composite alternatives, making it ideal for critical applications including grounding systems, data centers, and high-current industrial machinery where connection integrity directly impacts operational safety and efficiency.
Manufactured from 99.9% pure ETP copper (C11000 alloy), the lug delivers exceptional conductivity of 97% IACS for minimal power loss across the connection. This high conductivity ensures efficient current transfer even in high-amperage applications, reducing resistive heating that can degrade connection performance over time.
The copper undergoes a precise annealing process that achieves a hardness of HV 65-85, ensuring uniform deformation during crimping for a gas-tight seal with conductor strands. This annealing process maintains conductivity while enhancing ductility, allowing the lug to conform perfectly to conductor surfaces without cracking or splitting.
The lug features a bright tin plating (8-12 µm thickness) on all exposed surfaces, providing superior corrosion resistance compared to bare copper. This plating protects against atmospheric oxidation, industrial pollutants, and moisture ingress, maintaining low contact resistance even in harsh environments.
Featuring a cylindrical barrel with internal serrations and a flat terminal palm, the lug is precision-machined to ensure consistent dimensions and optimal crimp performance. The terminal palm includes accurately positioned bolt holes (M5 to M24) with chamfered edges to prevent bolt damage during installation.
In electrical substations, data centers, and healthcare facilities, the lug provides essential grounding connections for equipment, ensuring proper fault current dissipation and personnel safety. Its high conductivity makes it ideal for sensitive grounding applications where low resistance is mandatory.
Solar and wind energy systems employ the lug for connecting copper conductors to inverter terminals and combiner boxes, ensuring efficient power transfer from generation systems to the electrical grid or storage systems.
Electrical contractors specify the lug for high-load commercial applications including high-rise buildings, shopping centers, and sports facilities, where it connects feeder cables to distribution panels and busbars in accordance with strict electrical codes.
The 630 mm² size supports continuous current handling up to 1250A under ambient conditions of 30°C, with derating factors applied for higher temperatures in accordance with NEC and IEC standards. This high current capacity makes it suitable for large commercial and industrial applications.
Installation requires hexagonal crimp dies matched to the conductor size, used with hydraulic tools delivering 15-40 tons of force depending on lug size. Proper crimping achieves a contact resistance of ≤5 µΩ when measured in accordance with UL 486B test procedures.
No, this lug is specifically designed for copper conductors only. For aluminum conductors, use a dedicated bi-metal crimp lug to prevent galvanic corrosion and ensure proper connection performance. Mixing copper lugs with aluminum conductors without proper isolation will void certifications.
Store the lug in a dry environment at temperatures between 5°C and 30°C to prevent moisture accumulation. The tin-plated surface provides up to 24 months of corrosion protection in storage when kept in original packaging, after which visual inspection for oxidation is recommended before use.
