Bimetallic Terminals Can Reduce Loosening Caused By Thermal Expansion And Contraction.

bimetal terminal lug employs a copper-aluminum composite structure design. Because aluminum has a significantly higher coefficient of thermal expansion than copper, the two materials expand and contract differently with temperature changes. This difference is cleverly utilized to give the bimetallic lugs price adaptive mechanical properties.

bimetallic lugs price list At high temperatures, the aluminum portion expands rapidly, while the copper portion expands relatively slowly, creating a dynamic stress balance between the two. When temperatures drop, the aluminum portion contracts rapidly, but the copper portion contracts less. The cable lug bimetal's "self-adjusting" capability ensures that the wiring connection always maintains a relatively tight crimp.
