Summary:The invention discloses a high-voltage bushing capable of withstanding ultralow temperature and ultrahigh temperature. The high-voltage bushing comprises a main insulating bushing body, an umbrella cover and a mounting flange are arranged on the main insulating bushing body, the main insulating bushing body is made of a ceramic material, and an inner hole of the main insulating bushing body is covered with semiconductor glaze. Epoxy impregnated carbon fibers or sintered semiconductor glaze is wound on the outer surface of the main insulating sleeve and located at the mounting position of the mounting flange to form an equipotential layer of a semiconductor, a grounding electrode is correspondingly formed on the outer surface of the main insulating sleeve, and the mounting flange is glued to the grounding electrode. And one end of the umbrella cover wraps the grounding electrode exposed out of one side of the mounting flange. The bushing has good electrical performance, good mechanical performance and excellen
