Abstract

The invention provides a high-temperature-resistant varnished wire. The high-temperature-resistant varnished wire comprises a bare copper wire and a high-temperature-resistant varnished wire paint layer; and the high-temperature-resistant varnished wire paint layer is a composite layer, and comprises a heat-resistant insulating inner layer, a heat-resistant adhesive outer layer and a heat-resistant middle layer for gluing the inner layer and the outer layer, from inside to outside. The varnished wire prepared by the invention has high heat resistance, and is applicable to winding wires of high-voltage, low-voltage and medium-voltage high-capacity motor electric appliance products.

Description

technical field [0001] The invention relates to a high temperature resistant enameled wire, which belongs to the technical field of electrical materials. 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. [0003] At present, there are more than a thousand enameled wire manufacturers in my country, and the annual production capacity has exceeded 10,000 tons. But in general, the situation...
