Bimetallic Terminal Block Design Guidelines: Material, Current, And Temperature Rise Analysis

In electrical systems, bimetallic lugs price follows strict cross-sectional calculation standards during the design process. Designers precisely determine the terminal cross-section based on the rated current and conductor material properties to control the resistance distribution between the conductor and the terminal. The terminal cross-section is directly related to the current carrying capacity; insufficient cross-section may lead to localized heating, while excessive cross-section increases manufacturing costs and material consumption.

Material and cross-section matching

bimetallic lugs price list is typically composed of two different metallic materials. Different metals have different resistivities and coefficients of thermal expansion, and the terminal cross-section must be designed for rated conditions.

• Resistivity Calculation: During the design process, engineers determine the required cross-section for each metal based on the resistivity of copper, aluminum, or copper-aluminum composites.

• Temperature Rise Analysis: By simulating temperature changes under rated current, it is determined whether the cross-section meets the thermal performance requirements.

• Mechanical Strength Considerations: Terminals bear bolt tightening forces during connection; the cross-section design must balance conductivity and mechanical properties.

Current Carrying Capacity and Heat Dissipation Characteristics

The cross-section design of the cable lug bimetal terminal not only relates to the conductor's current carrying capacity but also affects system thermal management. Appropriate cross-section distribution can keep the overall terminal temperature within the design range, ensuring stable current transmission.

Through precise cross-sectional design, bimetallic lugs maintains stable electrical performance under rated conditions. Engineers combine material parameters, temperature rise testing, and mechanical strength analysis during the design phase to develop a complete cross-sectional design scheme.
