XHP-70kn/80kn/100kn/120kn/160kn/210kn Fog type anti-polluted porcelain disc suspension insulator
Bell jar shaped pollution resistant suspension insulator, with electromechanical failure load of 100kN, slot connection and ordinary insulator have the same electromechanical strength grade. It has large climbing distance and good wet flashing performance, and is suitable for coastal areas and rainy areas. High voltage line pollution resistant disc-shaped suspension porcelain insulator is suitable for industrial dust, chemical industry, saline alkali, coastal and foggy areas. It is used for insulation and fixed conductors on high-voltage overhead transmission and distribution lines. It is generally assembled into insulator strings for power lines in different voltage levels and different pollution areas.

Product comparison
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
