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

One such major practice is the application of the process of placing a bi-metallic washer or compound to prevent metal-to-metal contact. An anti-oxidation compound in use will provide a corrosion decrease as well as a stable electrical connection. The second big practice is the employment of correct crimping procedure with the appropriate tool in an effort to produce a secure mechanical connection between the cable and lug. Under-crimping and over-crimping will lead to bad conductivity, over-heating, and even breakdown in the connection. The second one is also crucial to make sure the lug size is equal to the cable gauge so that no loose connections are formed which can form sparking or resistances.

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