AI Technical Summary

Problems solved by technology

The existing porcelain insulators have the following problems: 1. The anti-pollution flashover effect of the existing porcelain insulators is poor, and accidents will occur frequently after the porcelain insulator is damaged, and only the outer layer of the porcelain insulator is coated with an anti-pollution flashover coating , the anti-fouling flashover coating will be damaged after long-term use; 2. In high-altitude areas, there are often cold areas, and the outside of the porcelain insulator will freeze during use, and ice water will also cause anti-fouling flashover on the surface of the porcelain insulator layers cause wear

Description

technical field [0001] The invention relates to the technical field of electric porcelain insulators, in particular to an anti-pollution rod-shaped suspension porcelain 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. Insulators made of ceramics are porcelain insulators. [0003] Due to the increasing demand for electricity, the transmission capacity and voltage are also increasing; but with ...
