Alcohol soluble type enameled round aluminum wire chemical performance is one of the main types of electromagnetic wire. The bare wire composed of conductor and insulating layer 2 is annealed and softened, then it is repeatedly sprayed and baked. However, it is not easy to meet the production requirements of the standard and the requirements of customers. It is affected by the quality of raw materials, processing parameters, production equipment and environmental factors. Therefore, the quality characteristics of various enameled wires are different But they all have high temperature resistance, mechanical performance, electrical and chemical performance and excellent freezing resistance. They are suitable for refrigerating equipment working at 200 ℃ for a long time, electrical equipment corroded by chemicals, dry-type transformer, oil immersed transformer, epoxy casting transformer and other mechanical and electrical equipment.
