Product Application
The double-layer umbrella pollution resistant insulator has large creepage distance, open umbrella type, smooth inside and outside the skirt, low ash deposition rate, good rain and rain self-cleaning performance, open umbrella type, large creepage distance and smooth in the group. Because the product design adopts the principle of air flow unimpeded, it has the characteristics of good rain and rain self-cleaning performance, low dirt deposition rate and easy cleaning. It is suitable for AC and DC transmission lines in heavily polluted, high-altitude and desert dry areas.

Double umbrella pollution resistant insulator is suitable for industrial dust, chemical industry, saline alkali, coastal and foggy areas. The umbrella is open, the creepage distance is large, and the skirt is smooth. Because the product design adopts the principle of air flow unimpeded, it has the characteristics of good wind and rain self-cleaning performance, low pollution accumulation rate and easy cleaning. It is suitable for AC and DC transmission lines in heavily polluted, high altitude and desert dry areas.
High voltage line pollution resistant disc suspension insulator is suitable for industrial dust, chemical industry, saline alkali, coastal and foggy areas. It is generally assembled into insulator strings for power lines in different voltage levels and different pollution areas.
According to its shape, pollution resistant insulators are divided into double-layer umbrella type, bell jar type and straw hat type. Double umbrella pollution resistant insulator has large creepage distance, open umbrella, smooth inside and outside skirt, low ash deposition rate and good wind and rain self-cleaning performance; The bell jar type pollution resistant suspension insulator has good antifouling performance by using the different periods of moisture in the umbrella and the discharge inhibition effect of the high edge under the umbrella; The diameter of straw hat type pollution resistant suspension insulator is large. Generally, it is placed at the top of suspension string, which plays a good role in preventing bird damage and penetrating icing
