Abstract:
A composite insulator comprising:an insulating rod;end fittings crimped to opposite end portions of said insulating rod, each of said end fittings having a flange extending radially outwardly from an outer periphery thereof; andan integrally molded layer of elastic insulating material disposed around an outer peripheral surface of said insulating rod and around a portion of an outer peripheral surface of each of said end fittings such that said integral layer of elastic insulating material contacts said outer peripheral surfaces at substantially all points thereof and extends up to and between said flanges, wherein a thickness of said integral layer of elastic insulating material disposed around said end fittings is about 30% to about 40% thicker than substantially the entire remainder of said integral layer of elastic insulating material disposed around said insulating rod, to thereby prevent flashover between said end fittings through any portion of said elastic insulating material.
