The invention discloses a 220kV-voltage-level anti-icing composite insulator. The problem that adjacent umbrella skirts of a 220kV-voltage-level electric transmission line composite insulator in a zone where icing is severe can be easily subjected to icing bridging is solved. The 220kV-voltage-level anti-icing composite insulator comprises 44 insulator umbrellas which are evenly arranged from a low-voltage-side bowl head to a high-voltage-side ball head, the 44 insulator umbrellas are arrayed according to the following sequence that a first insulator super-large umbrella (1) is arranged on the right side of the low-voltage-side bowl head, 8 insulator small umbrellas and 7 insulator large umbrellas are arranged at intervals on the right side of the first insulator super-large umbrella (1) according to the one-small-umbrella-one-large-umbrella rule that the insulator small umbrellas are arranged first, the insulator large umbrellas are arranged, and then the insulator small umbrellas are arranged, a second insulator super-large umbrella (9) is arranged on the right side of an eighth insulator small umbrella, the three-super-umbrella-7-7-5-structural-type anti-icing composite insulator is arranged according to the rule, and the numbers represent the numbers of the large umbrellas between the super-large umbrellas. The effective creep distance of the insulator is guaranteed, and the frequency of icing flashover accidents is greatly lowered.
