In order to guide the application of composite cross arms in heavy ice areas, we investigated the icing characteristics of glass fiber reinforced composite material and composite insulated crossarms in this paper. The results show that the icing amount and ice flashover voltage of blank sample under vertical suspension are better than that of horizontal suspension, and its icing amount is less than that of pure aluminum rod and Q345 steel rod with the corresponding hydrophilic. The icing amount of the composite material coated with PRTV coating is less than that of the blank sample, its flashover voltage increases sharply; the ice surface adhesion value is the least, which is 19% of ice surface adhesion value of pure aluminum rod, while the ice surface adhesion value of the blank sample is 78% of pure aluminum rod. The ice coating characteristics of the silicone rubber composite insulated crossarm are just the opposite of that of the composite material sample. Compared with vertical suspending the same composite insulator, when the insulators are horizontal suspending, the icing amount of composite insulated crossarm suspension reduces by 30%, and the flashover voltage increases by 51%.
