Bi-Metal Lugs

Bi-Metal Lugs are essential components used to connect aluminum conductors to copper busbars or terminals, effectively eliminating galvanic corrosion and ensuring stable electrical conductivity. These lugs are manufactured using a friction-welded aluminum barrel and a copper palm, allowing a secure and reliable joint between dissimilar metals.

Key features of our bi-metal lugs include:

• Superior conductivity for minimal resistance and energy loss

• Anti-corrosive protection to prevent oxidation at connection points

• Friction-welded construction ensuring a strong and seamless bond

• Tin-plated finish for enhanced durability and extended service life

• Available in a wide range of sizes to suit various cable diameters and applications

Widely used in transformers, switchgears, substations, power distribution panels, and renewable energy systems, bi-metal lugs help maintain safe and efficient power flow in environments where both copper and aluminum components are in use.

At Star Freight & Trading FZC LLC, we offer bi-metal lugs that comply with international electrical and mechanical standards, ensuring long-term reliability in high-load and high-temperature conditions.

Frequently Asked Questions (FAQs) – Bi-Metal Lugs

1. 1. 1. 1. What are Bi-Metal Lugs used for?
            Bi-Metal Lugs are used to connect aluminum conductors to copper bus bars or terminals, ensuring a secure and reliable joint in electrical installations.
         2. Why are Bi-Metal Lugs necessary?
            They help prevent galvanic corrosion, which occurs when aluminum and copper come into direct contact, ensuring long-term electrical stability.
         3. How are Bi-Metal Lugs constructed?
            They are made from high-purity aluminum (barrel) and copper (palm) that are bonded together using a friction welding process for high conductivity and durability.
         4. Where are Bi-Metal Lugs commonly used?
            These lugs are widely used in power distribution networks, substations, transformers, switchgear, and industrial electrical systems.
         5. How do I install Bi-Metal Lugs?
            Installation involves cleaning the conductors, applying an appropriate oxide-inhibiting compound, inserting the aluminum cable into the lug barrel, crimping securely, and tightening the copper end to the terminal.
