BI METALLIC LUGS are constructed to ensure stable electrical and mechanical characteristics despite the thermal cycles and loadings, which are typical in high-current and industrial applications, over and over again. The two metals usually used in the manufacture of bi-metallic lugs, aluminium and copper, have different coefficients of thermal expansion. Direct connections without proper transition components can loosen over time, increasing contact resistance and risking overheating.

BI METALLIC LUGS thus overcome this limitation through their very design and manufacturing processes. The aluminum barrel and copper palm are joined together by means of friction welding among other similar methods,
