[0002] Enameled wire is the most representative product in electronic wire materials. Enameled wire is a main variety of winding wire, which is composed of a conductor and an insulating layer. After the bare wire is annealed and softened, it is then coated with paint and baked multiple times. However, it is not easy to produce products that meet both the standard requirements and the 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.

[0003] In the prior art, the outer protective layer of enameled round copper wire is mostly made of polyurethane, which only plays a role of wear resistance and isolation, and is designed with a single-layer structure, without the functions of flame retardancy and radiation resistance. As a result, it is easy to be damaged in case of fire, and at the same time, it cannot improve the radiation resistance of electronic products, resulting in low protection performance of the wire.
