Description

technical field [0001] The invention relates to the field of insulators, in particular to an aging-resistant ceramic insulator and a preparation method thereof. Background technique [0002] An insulator is a device installed between conductors of different potentials or between a conductor and a component at ground potential, capable of withstanding voltage and mechanical stress. It is a special insulation control 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. [0003] When the ceramic insulators in the prior art are used outdoors, the running insulators are always affected by various pollution sources in the atmosphere, which accelerates their aging rate and is prone to pollution flash...
