Bi-metallic lugs are generally applied for connecting aluminum and copper conductors, avoiding galvanic corrosion and allowing smooth power transmission. However, in high-vibration applications like industrial machinery, transportation networks, and power distribution grids, such lugs have their own challenges.. Unless properly installed and maintained, vibrations can lead to loose contacts, higher resistance, and even failures, compromising electrical safety and performance.

A principal worry is relaxation of the bonds with time through mechanical stress. Micro-movements can also result from the dissimilar rates of thermal expansion between aluminum and copper, which increase the chances of connection failure. Additionally, fretting corrosion is possible through sustained vibrations, causing minute movement at the point of contact and creating oxidation with reduced conductivity. In order to minimize these risks, proper crimping processes with high-quality compression equipment must be utilized to provide a good mechanical bond. Additionally, application of an anti-oxidation compound at the contact points can also minimize corrosion and maximize conductivity.

For those who need reliable bi-metallic connections in severe conditions, Pioneer Powers provides heavy-duty bi-metallic lugs for optimum durability and power efficiency. Taking advantage of the use of washers that withstand vibration, fasteners with controllable torque, and performing maintenance checks on a regular basis may also enhance stability in connections. With these practices, companies may attain long-lived, secure, and efficient electricity performance even on the most high-vibration loads.
