The question is pertinent, considering the difficulties involved in combining metals when doing electrical connections if not properly executed.
The bi-metallic lugs by Pioneer Power specifically address this problem. They have an aluminum barrel and a copper palm, bonded together through friction welding. This innovative combination allows for a good secure connection of aluminum and copper conductors without galvanic corrosion, which is a common problem due to the direct contact of different metals.
The durability of the lugs contributes to their reliability. The connection point is kept at a reduced electrical resistance with the design to ensure that electric current flows more efficiently. Another advantage is better tolerance to variations in temperature and, therefore to overheating for power distribution.
There is always the mixed metal cable with Pioneer Power bi-metallic lugs which means long-lasting and corrosion-free connections to ensure safety and efficiency in electrical systems.
