In order to solve the electrochemical corrosion of the end of the enamelled copper clad aluminum wire, the method is to block the end from the atmosphere. At present, the following two methods can be mainly adopted.
1. Electroplating method: It is to plate a layer of copper on the joints of the enamelled copper-clad aluminum wire, but it will waste a lot of time. However, it is not a big problem in the company that produces enamelled copper-clad aluminum wire, because many joints can be plated together.
2. Copper-colored quick-drying paint: dries within two minutes, and the color is appropriate to the copper. This is very convenient for users who use enamelled copper clad aluminum wire. Because the user can cut the wiring at any part, just apply quick-drying paint on the section to avoid corrosion.
At present, enamelled copper clad aluminum wire has been widely used in the cable television industry. It has the advantages of rational use of natural resources, lower production costs, and convenient engineering construction.
