Abstract
An electrical insulator in the form of a pintype insulator has a load sustaining mechanical core and a dielectric sheath overlying the mechanical core to protect the mechanical core from the weather. The mechanical core is constructed of a load sustaining dielectric material which is different from the dielectric material of the sheath. The mechanical core has a profiled outer surface with a top groove, two side grooves, an annular rib and an axially extending threaded bore. The dielectric sheath is applied over the mechanical core as thin as practical to minimize the amount of sheath material being used. However, the dielectrical sheath is molded on the mechanical core to form a pair of weathersheds which can either extend radially outwardly therefrom or substantially downwardly therefrom in the form of vertical sheds.
