Abstract

A staggered shed type composite insulator includes a core member and a housing provided around the outer peripheral face of the core member and made of an insulating polymeric material, the housing comprising large-diameter shed portions, small-diameter shed portions and sheath portions arranged such that the large-diameter shed portions and the small-diameter shed portion are alternatively arranged via the respective sheath portions, wherein "1/p" is in a range from 4.3 to 5.0 in which "1" and "p" are a unit surface-leakage distance and an axial unit length of the housing, respectively.
