WHAT ARE THE COMMON FAILURE MODES OF BI-METALLIC LUGS, AND HOW CAN THEY BE PREVENTED TO ENSURE LONG-TERM RELIABILITY IN ELECTRICAL SYSTEMS?

Bi-metallic lugs are commonly employed within electrical systems to join aluminum and copper conductors in order to facilitate effective power transfer and avoid galvanic corrosion. Nevertheless, the lugs can fail after a while due to a number of causes such as corrosion, thermal growth, mechanical tension, and faulty fitting. Corrosion results fro
