Abstract
A method of manufacturing an electrical rod insulator for supporting an electrical conductor and comprising an insulating core obtained by molding and having a top end and a bottom end with a bore for receiving said rod in an axial direction, and covered in a molded covering having a groove for supporting said electrical conductor, wherein the core is molded in such a manner that its outside surface defines radial ribs extending along the axial direction from the top end of the core, said ribs being spaced apart from one another by a distance that is constant and substantially equal to the thickness of the core. The method makes it possible to avoid problems associated with molding large thicknesses when making a composite insulator having better mechanical and electrical properties at low cost.
