Abstract

The invention discloses a polyimide enameled wire. The section of the enameled wire is rectangular and has a five-layer structure. The length of the rectangle is 1.2 to 1.3 times the width. The outside of the alloy conductor wire core has a copper cladding layer, the outside of the copper cladding layer has a tin cladding layer, the outside of the tin cladding layer has a polyimide paint layer, and the polyimide paint layer There is a heat-conducting silica gel layer on the outside, and the thickness of the heat-conducting silica gel layer is 0.3-0.4 mm. Through the above method, the present invention has a simple and reasonable structure, good heat resistance, a rectangular cross-section, and a relatively compact winding group when in use, and has good heat transfer and thermal conductivity.

Description

technical field [0001] The invention relates to the technical field of enameled wires, in particular to a polyimide enameled wire. Background technique [0002] Enameled wire is the main raw material of products such as motors, electrical appliances and household appliances. Especially in recent years, the electric power industry has achieved sustained and rapid growth, and the rapid development of household appliances has brought a wider field of application of enameled wire, followed by Higher requirements are put forward for enameled wire. The existing enameled wire has poor heat resistance and needs to be improved. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a polyimide enameled wire with simple and reasonable structure, good heat resistance, rectangular cross-section, compact winding group when in use, and good thermal conductivity. [0004] In order to solve the above-mentioned technical problems, a ...
