Description

technical field

[0001] The invention relates to an electrical insulating material, in particular to an electrical insulating thermoplastic resin composition and a preparation method thereof. Background technique

[0002] At present, electrical packaging generally adopts solid insulation packaging. Thermosetting epoxy resin or silicon micropowder is mainly used for solid insulation packaging of medium voltage switch primary equipment, such as vacuum circuit breakers, solid insulation ring network cabinets, and switchgears. Thermosetting epoxy resin is used. For example, the traditional embedded vacuum circuit breaker uses thermosetting epoxy resin as the packaging material, and the conductive parts such as the vacuum interrupter and the conductive terminal are encapsulated into an embedded pole through the automatic pressure gel process (APG), and then assembled into a circuit breaker. . The conductive parts such as the vacuum interrupter and conductive terminals in the sol...
