As transformers generate high temperature during operation, the use of 220 degree enameled aluminum wire ensures that the coils work properly in a high temperature environment and prevents them from heating up too much, resulting in burned out coils or performance degradation.

Transformer coils are wound by enameled wire, which is a type of wire whose wire core is covered by multiple layers of insulating enamel. This insulation protects the wire core from short circuits or electric shocks and provides some mechanical strength.

220 Degree Enameled Aluminum Wire is classified according to its temperature resistance rating.220 Degree means that the enameled wire is able to withstand temperatures of up to 220 degrees Celsius for extended periods of time without damage. This makes it suitable for transformer applications in high temperature environments.


There are some advantages to using aluminum wire. Firstly, aluminum is a lightweight metal and the lower density of aluminum wire compared to copper wire reduces the weight of the entire transformer. Secondly, aluminum wire has good electrical conductivity and although the conductivity is lower than copper, it can meet the current loading requirements of the transformer in a properly designed coil. In addition, aluminum wire is relatively inexpensive and can reduce transformer manufacturing costs.

When using 220 degree enameled aluminum wire, there are some factors to keep in mind. First, due to the lower conductivity of aluminum wire, it may be necessary to use larger diameter aluminum wire than copper wire in the same application in order to meet the same current loading requirements. Second, because aluminum wire is susceptible to oxidation, additional measures may be required to protect the surface of the wire from the effects of oxidation on performance. Finally, aluminum wire has a large coefficient of linear expansion, so the effects of thermal expansion on the coil need to be considered in coil design.

Overall, 220 degree enameled aluminum wire can be used for transformer coils in high temperature environments with good temperature resistance and conductivity.
