How Does the Design of Bi Metallic Lugs Enhance Their Performance?
Blog Article
The Bi Metallic Lugs' innovative structure plays an important function in maintaining secure, efficient, and durable electrical connections between copper terminals and aluminium conductors. Each component of their structure is designed to counteract the issues associated with mixed-metal connections, which makes them better than conventional lugs for certain applications.
Dual-Metal Composition:
Bi Metallic Lugs consist of an aluminium barrel and a copper palm. The two-metal structure enables smooth connection of aluminium cables with copper busbars without metal-to-metal contact, eliminating galvanic corrosion.
Friction-Welded Joint:
Aluminium-to-copper transition is done through precision friction welding. The process forms a strong, imperfection-free joint that maintains mechanical stability and higher electrical conductivity while withstanding separation or crack under stress.
Barrel Design:
The aluminium barrel features an internal serration pattern or grooves. These improve grip strength on the aluminium conductor, ensuring against slippage, loosening, and optimizing current conduction through maximum surface contact.
Copper Palm Construction
Copper Palm is specifically designed to provide a flat and level surface to connect seamlessly with copper busbars or terminals. Its large contact area minimizes electrical resistance and aids in effective heat dissipation during high current conduction.
Anti-Oxidation Features:
Several Bi Metallic Lugs are supplied with anti-oxidation finishes such as tin or nickel plating, or are made from extremely pure metals to withstand environmental corrosion, thereby lengthening their service life under severe conditions.
Optimized for Compression Crimping:
The barrel of the lug is designed to accommodate secure compression crimping to provide tight and permanent cable bonding. This minimizes the risk of loosening caused by mechanical vibration or thermal expansion.
Broad Range of Sizes and Configurations:
Bi Metallic Lugs come in a range of sizes and configurations suitable for various cable diameters, current ratings, and terminal sizes, thus being industry-versatile.
Compatibility with Thermal Expansion:
The construction enables the aluminium and copper parts to accommodate their individual thermal expansions without inducing stress cracks or loosening, ensuring connection integrity with temperature changes.
Conclusion:
The carefully engineered construction of Bi Metallic Lugs improves electrical performance, resistance to corrosion, mechanical strength, and thermal stability. They become absolute necessities in contemporary electrical systems where dual-metal connections are needed.
