An insulated composite aluminum enamelled wire

Abstract

The invention discloses an insulating composite aluminum enameled wire, belonging to the enameled wire material field, comprising a conductor, wherein the conductor is a composite aluminum wire, and the conductor surface is sequentially provided with a primer layer, a first high-temperature resistant layer, an insulating layer, a second high-temperature resistant layer and an abrasion-resistant layer from the inside to the outside, and the primer layer is polyphthalamide. An imide paint, wherein the first high temperature resistant layer is composed of acetal, phenolic, melamine, polypyrrole and graphite ladder polymer, the insulating layer is composed of silicone resin, copolyphenol and polypropylene, the second high temperature resistant layer is composed of ceramic fiber and polyphenylene, and the wear resistant layer is composed of polytetrafluoroethylene, silicon carbide, graphene and epoxy resin. The insulation composite aluminum enameled wire improves the high temperature resistance and the wear resistance.

Description

technical field [0001] The invention relates to an enameled wire material, in particular to an insulating composite aluminum enameled wire. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, thermal properties four major properties. 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 of...

AI Technical Summary

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
