The invention discloses a 110kV-voltage-level anti-icing composite insulator. The problem that adjacent umbrella skirts of a 110kV-voltage-level electric transmission line composite insulator in a zone where icing is severe can be easily subjected to icing bridging is solved. The 110kV-voltage-level anti-icing composite insulator comprises 26 insulator umbrellas which are evenly arranged from a low-voltage-side bowl head to a high-voltage-side ball head, the 26 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, a first insulator large umbrella (2) is arranged on the right side of the first insulator super-large umbrella (1), two insulator small umbrellas are arranged on the right side of the first insulator large umbrella (2) in sequence, then a second insulator large umbrella (3) is arranged, according to the rule, the four-super-large-umbrella-2(2 and 3)-2(1 and 2)-2(2 and 3)-1(2)-structure-type anti-icing composite insulator is arranged, wherein, the numbers outside the parentheses represent the numbers of the super-large umbrellas, and the numbers inside the parentheses represent the numbers of the small umbrellas. The effective creep distance of the insulator is guaranteed, and the frequency of icing flashover accidents is greatly lowered.
