Problems solved by technology

In this case, a high surge voltage will be generated in the coil of the electrical equipment, and partial discharge will occur between the wires or to the ground. The wire insulation is easily eroded by high temperature, and the insulation is damaged or even burned. , causing certain safety hazards to the normal use of electrical equipment
[0003] The current preparation process of wire insulation is relatively complicated, the cost is high, and the flame retardancy is not perfect enough, which needs further research and development

Abstract

The invention discloses an electric line insulating skin with an inflaming retarding effect. The insulating skin comprises a surface layer, a middle layer and a bottom layer. The surface layer is a blended fabric layer composed of glass fibers and nylon fibers, the middle layer is a fire-resistant coating layer and the bottom layer is a woven-cloth layer. The middle layer coats the bottom layer. The surface layer adheres onto the middle layer. The design of a multiple-layer composite structure is adopted in the insulating skin, comprehensive performance is superior, the inflaming retarding effect is good, the service life of an electric line is greatly prolonged and the safety performance of the electric line is greatly improved. Thus, electric equipment is safer and more reliable to use. Meanwhile, the insulating skin is flexible and high in plasticity and strength. Covering the electric line is easy to perform.

Description

technical field [0001] The invention relates to a wire insulation skin, in particular to a wire insulation skin with a flame-retardant effect, and belongs to the technical field of insulating materials. Background technique [0002] In the coils of electrical equipment such as rotating machines and transformers, insulated wires with metal conductors covered with insulation are used. Most of the insulation has good adhesion to the conductor, electrical insulation, corrosion resistance and heat resistance. and other performance. In recent years, in accordance with the requirements for miniaturization, high performance, and energy saving of electrical equipment, inverter control of electrical appliances with high voltage and high current has been widely used. In this case, a high surge voltage will be generated in the coil of the electrical equipment, and partial discharge will occur between the wires or to the ground. The wire insulation is easily eroded by high temperature, ...
