Enameled wire is a main variety of winding wire. It consists of two parts: conductor and insulation layer. The bare wire is annealed and softened, and then painted and baked multiple times. However, it is not easy to produce products that meet the requirements of the standard and meet the requirements of customers. It is affected by factors such as the quality of raw materials, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires are different, but all Mechanical properties, chemical properties, electrical properties, and thermal properties.
