Bimetallic Terminals In Electrical Connections At Aluminum-copper Junctions

To address the drawbacks of direct aluminum-copper connections, product bi metallic cable lugs was developed. This product employs a friction welding process to form a metallurgical bond at the copper-aluminum interface, blocking the intrusion path of the electrolyte. During the welding process, bimetal cable lug fuses the atoms of the two metals to create a stable copper-aluminum alloy transition layer, fundamentally eliminating the possibility of galvanic cell reactions.

In practical applications on the low-voltage side of transformers, bimetal terminal lug is available in two specifications: Chinese standard and European standard. The European standard bimetallic lugs price has conductive grease built into the tube wall and a dustproof and sealed design at the bottom, making it suitable for harsh working environments and new energy projects. The national standard bimetallic lugs price list is relatively economical in cost, has complete double-hole crimping function, and is suitable for standard power distribution projects.

During the actual installation process, the cable lug bimetal needs to match the structural dimensions and conductor cross-section specifications of the low-voltage side of the transformer to facilitate connection with aluminum conductors and copper busbars. The design considers common conductor combinations found in transformers and distribution cabinets, ensuring stable metal contact surfaces at the connection nodes and smooth integration with other power distribution devices.
