Description

technical field [0001] The invention relates to insulating paper, in particular to a modified methyl methacrylate insulating paper. Background technique [0002] Insulating paper is a general term for electrical insulating paper. It is used as insulating material for various electrical equipment such as cables and coils. In addition to having good insulation properties and mechanical strength, each has its own characteristics. [0003] Since the insulating paper used in the high-voltage package cannot be replaced during operation, its mechanical and insulating properties will deteriorate under the stimulation of the external environment, which will shorten the life of the high-voltage package. Therefore, the insulating paper with excellent performance is manufactured It is of great significance to prolong the service life of high-voltage packs and promote the development of voltage and electricity in my country. Contents of the invention [0004] Based on the technical p...
