Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then painted and baked multiple times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. Enameled wire is the main raw material for products such as motors, electrical appliances, and household appliances. In particular, in recent years, the power industry has achieved sustained and rapid growth, and the rapid development of household appliances has brought a broader field of application for enameled wire, which in turn has higher requirements for enameled wire.
