Description

technical field [0001] The invention relates to the technical field of insulators, in particular to an aging-resistant ceramic insulator and a preparation method thereof. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. Insulators were mostly used on utility poles in the early years, and gradually developed into high-voltage wire connection towers where many disc-shaped insulators were hung at one end. It was used to increase the creepage distance and was usually made of glass or ceramics. A device capable of withstanding voltage and mechanical stress installed between a conductor at a different potential or between a conductor and a grounded member. There are many types of insulators in different shapes. Although the structure and shape of different types of insulators are quite different, they are all composed of two parts: insulating parts and connecting fittings. [0003] Insulator...
