How Do Bi Metallic Lugs Prevent Galvanic Corrosion?
Blog Article
Galvanic corrosion is a critical issue in electrical applications where two different metals, like aluminium and copper, are in direct contact with each other. This electrochemical reaction leads to corrosion at the point of contact, causing the joint to weaken with time. Bi Metallic Lugs have been specifically engineered to avoid this issue and provide robust, long-lasting electrical connections.
Ways in Which Bi Metallic Lugs Avoid Galvanic Corrosion:
Utilization of Similar Metal Interfaces
Bi Metallic Lugs have an aluminium barrel for aluminium conductors and a copper palm for copper busbars or terminals. Thus, each metal contacts its respective material only, avoiding direct contact of aluminium to copper as well as resulting galvanic action.
Friction Welding Technology:
The join between the copper and aluminium parts of the lug is achieved through friction welding. The process creates a homogeneous, weld that is strong but not made with foreign material, minimizing the chances of electrochemical activity at the weld junction.
Anti-Oxidation Coating:
Some of the high-quality Bi Metallic Lugs feature anti-oxidation coatings or treatments that improve corrosion resistance and offer added protection in harsh environments like coastal or chemical industry.
Sealed Joint Construction:
The friction-welded joint's smooth and sealed appearance does not allow moisture or contaminants to penetrate the area of connection, further discouraging galvanic corrosion.
Long-Term Electrical Stability:
Since the interface is corrosion-free, Bi Metallic Lugs ensure long-term electrical stability with no risks of overheating, heightened resistance, or failure of the connection.
Ideal for Demanding Environments:
In power stations, petrochemical plants, and outdoor renewable energy systems where there is high humidity and pollution, Bi Metallic Lugs offer superior corrosion protection over direct metal-to-metal contact.
Conclusion:
Bi Metallic Lugs are designed with the purpose of avoiding galvanic corrosion by separating aluminium and copper interfaces, applying high-level friction welding, and ensuring strong sealing against environmental conditions. By doing so, the design provides durability, safety, and reliable performance in varying electrical systems.
