Abstract

The invention discloses a heat cycle-resistant enameled wire, relates to the technical field of enameled wire production, and includes an enameled wire body, the enameled wire includes a conductor, a reinforcement layer and a paint spray layer, the outer surface of the conductor is fixedly connected with a reinforcement layer, and the outer surface of the reinforcement layer is fixedly connected with a The paint layer, the reinforcement layer includes a heat conduction layer, a tensile layer and an aluminum foil layer. The invention also discloses a heat-resistant cycle enameled wire production process, which includes the following steps: step A: wire drawing; step B: cleaning; step C: annealing; step D: cooling insulation; step E: hot pressing; step F: coating Paint baking; step G: take-up. The present invention can significantly improve the overall mechanical strength and overall stability of the enameled wire through the heat conduction layer, the tensile layer and the aluminum foil layer, and can provide a cooling effect on the conductor through the heat conduction layer made of mica ice-cooling fiber layer. Heat dissipation effect, through the tensile layer of nylon material.

Description

technical field [0001] The invention relates to the technical field of enameled wire production, in particular to a heat cycle-resistant enameled wire and a production process. Background technique [0002] Enameled wire is the most representative product in electronic wire. Enameled wire is a main variety of winding wire. It is composed of two parts: conductor and insulating layer. Complete, and finally enter the winding process. [0003] However, the enameled wire in the prior art requires higher quality in the market, and the production process of the enameled wire in the prior art is relatively simple. Although the current enameled wire has mechanical properties, chemical properties, electrical properties and thermal properties, the overall use of the enameled wire The performance is not stable enough, and it is easy to affect the heat dissipation of the enameled wire due to the problem of poor internal heat conduction when used for a long time, which affects the overal...
