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
