Abstract

The invention discloses a heat-resistant circulating enameled wire, which relates to the technical field of enameled wire production and comprises an enameled wire body. The enameled wire comprises aconductor, a reinforcing layer and a paint spraying layer, wherein the outer surface of the conductor is fixedly connected with the reinforcing layer, the outer surface of the reinforcing layer is fixedly connected with the paint spraying layer, and the reinforcing layer comprises a heat conduction layer, a tensile layer and an aluminum foil layer. The invention further discloses a production process of the heat-resistant circulating enameled wire. The production process comprises the following steps of: A, wire drawing, B, cleaning, C, annealing, D, cooling and insulating, E, hot pressing, F,painting and baking, and G, wire take-up. The overall mechanical strength and the overall stability of the enameled wire can be remarkably improved through the heat conduction layer, the tensile layer and the aluminum foil layer, the conductor can be cooled through the heat conduction layer made of a mica ice-cold fiber layer material, meanwhile, high heat conduction efficiency is achieved, the heat dissipation effect of the enameled wire is improved, and the tensile layer made of a nylon material is adopted.

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...
