When joining copper wire to aluminum cable lugs on an electrical installation, best practice must be utilized to attain a safe, efficient, and durable joint. Copper and aluminum combined exhibit galvanic corrosion and this leads to electrical resistance and weakening of the connection strength with time. To avoid such issues, proper materials must be utilized, correct preparation techniques used, and follow install practices that allow for conductivity and system integrity.

One of these major practices is the application of the process of fitting a bi-metallic washer or compound to prevent metal-to-metal contact. An anti-oxidation compound in use will provide a corrosion reduction and a stable electrical connection. The second major practice is the application of correct crimping technique with the correct tool in an effort to provide a good mechanical connection between the lug and cable. Poor crimping will lead to the loosening, under-crimping, or over-crimping, causing poor conductivity, over-heating, and break down in the connection. The second one is also important to help guarantee the lug size is compatible with the cable gauge so no loose connections are formed that can form sparking or resistances.

For use in applications that require efficient and high-performance electrical contacts, Pioneer Powers has top-grade aluminum cable lugs to ensure efficient conductivity and long life. With proper installation based on proper means, their top-grade lugs ensure safety, efficiency, and longevity in industrial and power supply applications. By following strict proper best practice in cable-lug joints, businesses can minimize maintenance costs, achieve maximum electrical efficiency, and attain maximum installation life.
