Product details
70KN Anti-fog suspension porcelain insulators
(double-shed)
Double layer umbrella type pollution resistant suspension insulator, with electromechanical damage load of 70kN, is suitable for industrial dust, chemical industry, saline alkali, coastal and foggy areas. The umbrella type 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.
