Xinyu Enameled Aluminum Wires' Welding technology
With the large increase in copper prices in recent years, as well as its unstable current status, many customers have been greatly challenged by the cost of materials. So that the development of Enameled aluminum wire be accelerated and gained more attention.
Xinyu Enamelled Wire has been widely used in Europe, United States and Asia like Korea. In the 1990s, Europe and the United States use of aluminum enameled wire widely, and before the seventies of last century when China was difficult in recovering the copper resource, they use aluminum enameled wire in cable, power transformers, motors and other fields. From this point of view, the use of aluminum enameled wire should be no problem, but with the rich copper resources, and small different between copper and aluminum prices. People start using copper enameled wire and get great development in the short term . However, with the fluctuations in copper prices and the pressure of costs, aluminum surfaced and got rapid development.
With the current rapid development of technology, the basic welding technology of enameled aluminum wire has matured, good reliability.As long as the attention to some details of the welding process, such as welding temperature, protection after welding, etc, we can ensure the product quality of enameled aluminum wire.
Now we can generally divide welding into three types: a mechanical connection, such as terminals, copper, etc.; Second, brazing soldering flux and solder wire is the use of welding; third, high temperature brazing welding, this major used in large power transformers, general electrical unused.
Enameled aluminum wire is easier to be winded, because there is a solid on the surface of enameled aluminum wire, which make it has a good insulating effect and has a long life.
Because of the effect of insulating aluminum film layer, it’s heat-resistant temperature can be 20 degrees higher than others;
The greatest benefit of using aluminum is that it is 1/3 lighter than others which significantly keep the production costs lower, and it can attach to the solids easily, it can also reduce the freight and operation during transportation.
