Standard Application Of Bimetallic Terminals In Main Circuits

In modern power system design, bimetallic lugs is an important component of the main circuit connection. These terminals achieve stable electrical connections through combinations of different metals, maintaining continuous conductivity even under high current conditions. The selection of materials and structural design of bi metal cable lug have a direct impact on the overall operation of the main circuit.

Terminal Structure and Performance Requirements

bi metal lugs connectors is typically composed of two different conductive metals, with the contact interface between the materials being precisely processed.

• Metal Combination Method: Primarily copper-aluminum combination, with mechanical crimping technology at the contact interface to ensure the continuity of the conductive path.

• Dimensions and Installation Matching: Terminal dimensions strictly correspond to the main circuit conductor specifications, secured with bolts to ensure a stable mechanical connection.

• Temperature and Current Carrying Capacity: Under high-temperature operating conditions, the terminal contacts maintain low contact resistance to meet the current transmission requirements of the main circuit.

Maintenance and Inspection Standards

In electrical maintenance, bi metallic cable lugs needs to be inspected regularly to prevent abnormal operation from causing a decline in the performance of the main circuit.

• Regular Resistance Check: Contact resistance at terminal connections is measured using a micro-ohmmeter to identify potential problems.

• Tightening Force Assessment: Ensure the pressure between the bolt and terminal interface meets design requirements.

• Surface Condition Monitoring: Inspect metal surfaces for oxidation or corrosion and record maintenance history.

The bimetal cable lug device plays a role in stabilizing the connection in the main circuit. Through precise structural design and regular maintenance, the reliability of the terminals under various operating conditions can be guaranteed.
