Problems solved by technology

However, in the existing porcelain insulators, the mechanical strength of the porcelain parts is not high enough, the surface is not smooth enough, easy to stain, and difficult to clean, resulting in poor anti-fouling flashover effect; and the anti-corrosion treatment of the metal accessories of the insulator is mainly electro-galvanized and hot-dip. Zinc, these treatment techniques will pollute the environment, or affect the mechanical properties of the matrix, and the anti-corrosion performance is not good; therefore, the insulator is easily damaged, resulting in frequent accidents
At present, air pollution is becoming more and more serious, and accidents occur frequently, which greatly shortens the service life of ceramic insulators, and at the same time increases the maintenance cost of insulators, affects the normal operation of the railway power grid, and reduces economic benefits.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a line post type porcelain insulator and a preparation method thereof. Background technique [0002] Porcelain insulators have the advantages of high mechanical strength, stable chemical properties, good insulation performance, and good corrosion resistance, making them the most widely used in the insulator industry, and their use in railway traction network power systems is increasing. However, the natural environment in my country is relatively complex, and porcelain insulators are mostly used in outdoor or even field environments, so it is also required that porcelain insulator products can adapt to complex environmental conditions. However, in the existing porcelain insulators, the mechanical strength of the porcelain parts is not high enough, the surface is not smooth enough, easy to stain, and difficult to clean, resulting in poor anti-fouling flashover effect; and the a...
