In joining copper wires to aluminum cable lugs on an electrical installation, best practice must be adhered to in a bid to attain a safe, efficient, and long-lasting connection. Aluminum and copper combined have galvanic corrosion and this results in electrical resistance and weakening of the strength of the connection with time. In avoiding such issues, the right materials must be utilized, proper preparation methods utilized, and follow install practices that allow conductivity and system integrity.

One such major practice is employing the process of applying a bi-metallic washer or compound in a bid to prevent metal-to-metal contact. An anti-oxidation compound in use will offer a reduction in corrosion as well as a stable electrical contact. The second major practice is employing proper crimping technique using the correct tool in an effort to give a good mechanical bond between the lug and cable. Under-crimping and over-crimping will cause improper conductivity, overheating, and even collapse in the connection. The second is also essential to make sure that the lug size is consistent with the cable gauge so no loose connections form that can develop sparkings or resistances.

For use in applications requiring effective and high-performance electrical contacts, Pioneer Powers has high-grade aluminum cable lugs to ensure effective conductivity and long life. Through proper installation in accordance with proper means, their high-grade lugs ensure safety, effectiveness, and durability in power supply and industrial applications. By following strict proper best practice in cable-lug joints, businesses can lower maintenance costs, achieve maximum electrical efficiency, and achieve maximum installation life.
