Introduction to enameled aluminum wire
Enameled round aluminum wire is one of the main varieties of electromagnetic wire. It is made of bare wire composed of conductor and insulation layer 2, which is annealed and softened, and then repeatedly sprayed and baked. However, it is not easy to meet the production requirements of standards and products that meet customer requirements. It is affected by raw material quality, 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 properties, electrical properties and chemical properties and excellent freezing resistance. They are suitable for refrigeration equipment that works for a long time at 200℃, electrical equipment that is subject to chemical corrosion, dry transformers, oil-immersed transformers, epoxy casting transformers and other electromechanical equipment.
