Electrical Contact Considerations For Improving The Performance Of Bimetallic Terminal Block Systems

If the resistance value of the contact point of bi metallic cable lugs is too high, it will lead to energy loss and local heat generation. This heat accumulation may cause contact aging or hot spot effect during long-term operation, shortening the service life of bimetal cable lug. Low contact resistance helps maintain continuous current conduction between conductors and reduces thermal stress accumulation.

bimetal terminal lug performance in the face of environmental factors is equally important. Due to the difference in thermal expansion coefficients between aluminum and copper, they will experience microscopic displacement and stress during temperature cycling, placing higher demands on the electrical contact interface. By employing an optimized bimetallic structure, the risk of deformation at the material interface due to thermal stress can be reduced, thereby maintaining the integrity of the connection.
