Description

technical field [0001] The invention relates to a hanging insulator string for preventing wind deflection and pollution flashover, and belongs to the technical field of electric power fittings. Background technique [0002] After the transmission line conductor is affected by the strong wind, the suspension insulators of the straight pole tower will produce a certain angle of horizontal line wind deflection, which will discharge the insufficient distance between the cross arm or the main body of the pole tower, resulting in wind deflection failure of the transmission line, resulting in major hidden dangers in the safe operation of the line. In addition, insulators are affected by environmental factors such as industrial emissions and natural dust during normal operation, and pollution will gradually accumulate on the surface. Under dry conditions, the dirty layer will not conduct electricity and has little effect on the insulation strength; however, under weather conditions ...
