[0004] Among the relevant patents that have been applied in China, the patent "A Glass Insulator" (application number: 201210349297.3, publication date: 2013-01-16) discloses a composition formula of a glass insulator with good stability, but due to the Sintering after powder, high brittleness and poor bonding force, unable to retain basic working performance after zero-degree self-explosion, and because the powder remelting destroys the tempering effect and surface compressive stress brought by rapid cooling of the glass, the mechanical properties are poor and The service life is short (the surface compressive stress can significantly improve the service life), on the other hand, there is no toughening and impact resistance treatment, so that the glass insulator is easily damaged by phy

Description

technical field [0001] The invention relates to the field of electronic components, in particular to an impact-resistant ceramic insulator and a manufacturing method thereof. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. [0003] In the early years, insulators were mostly used on utility poles, 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, usually made of glass or ceramics, and was called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two roles must be guaranteed; at the same time, insulators should have sufficient electrical insulation strength, moisture resistance and high temperature resistance. [0004] Among the relevant patents that have been appl...
