Problems solved by technology
The main reason for these problems is that the enameled wire is required to be relatively soft during the motor winding process. Due to the long-term working characteristics of the motor, the temperature rise is relatively high.
However, the existing enameled wire generally has the defect of poor high temperature resistance. Since the existing enameled wire generally uses materials with a lower temperature resistance level, it is difficult to use the environment of high temperature resistant products, which can no longer meet the requirements of motor products. high temperature requirements

Abstract
The invention relates to a high-temperature-resistant enameled wire and an assembly thereof. The high-temperature-resistant enameled wire comprises a metal wire core. The surface of the metal wire core is coated with a shielding layer. The surface of the shielding layer is coated with a first heat-resistant layer. The surface of the first heat-resistant layer is coated with a second heat-resistant layer. The surface of the second heat-resistant layer is coated with an insulating paint layer. The surface of the insulating paint layer is wrapped by a nylon paint layer. According to the high-temperature-resistant enameled wire and the assembly, the structure of the double heat-resistant layers is adopted, the high-temperature-resistant performance of the enameled wire is greatly improved, a high high-temperature-resistant grade is achieved, the temperature rise requirement of a motor during work can be met, the safety performance is greatly improved, and the high-temperature-resistant enameled wire and the assembly are quite suitable for large-area application and popularization.
Description
technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a high-temperature-resistant enameled wire and components including the same. Background technique [0002] At present, high-temperature motors, load motors, air-conditioning compressors, parallel compressors, water dispensers and other products all need to use enameled wires. The enameled wires they use often have problems of inter-turn short circuit and excessive temperature rise that cause burnout. The main reason for these problems is that the enameled wire is required to be relatively soft during the motor winding process, and the temperature rise is high due to the long-term working characteristics of the motor. However, the existing enameled wire generally has the defect of poor high temperature resistance. Since the existing enameled wire generally uses materials with a lower temperature resistance level, it is difficult to use the environment of high te...
