AI Technical Summary
During the production process, the existing film wrapping process is unqualified, resulting in a reduced radiation resistance strength, which affects the service life.
Using a two-layer film coating structure, the first radiation-resistant layer and the second radiation-resistant layer are repeatedly coated in reverse and adhered by epoxy resin glue. The PA film covers the surface of the first radiation-resistant layer as a whole, and the PET tape is wrapped around the surface of the PA film to enhance protection.
Ensure that the surface of the enameled wire is completely covered and avoids leakage, thereby significantly improving the radiation resistance of the film wire and enhancing mechanical strength and wear resistance.

Abstract

Technical Field
[0001] The utility model belongs to the technical field of film-covered wires, and particularly relates to a film-covered wire with a strong radiation-resistant structure. Background Technique
[0002] A film-covered wire, also known as a Mai La wire or a Mai La wire, is a special electromagnetic wire. Its main feature is that one or more layers of synthetic films are coated on the outside of a wire or an enameled stranded wire as an insulating layer. Inside the film-covered wire is the wire or the enameled stranded wire, and the outside is tightly coated with a thin film insulating layer. The overlap rate of the thin film insulating layer can be adjusted according to specific requirements to ensure the insulation effect and mechanical properties.
[0003] The film-covered wire has excellent high-frequency performance and is suitable for electronic devices such as high-frequency transformers and high-power transformers. It can reduce signal attenuation and electromagnetic interference. Due to the excellent properties of the outer film, the film-covered wire can withstand higher temperatures and voltages, ensuring the stable operation of the device in harsh environments. However, during the production process of the film-covered wire, it has the effect of strong radiation resistance by coating the film. Due to the lack of the film coating process during production, the film is not qualifiedly coated on the surface of the enameled wire, resulting in a significant reduction in the radiation resistance of the film-covered wire and affecting its later service life.
