Abstract

A high voltage electrical insulator comprises an insulator body having a pair of upper and lower axially spaced terminals, the entire surface of the body being covered by a semiconductive layer providing a semiconductive path between the terminals, the insulator body providing at least one integral, downwardly depending, bell-shaped portion having an annular rim, said bell-shaped portion shrouding a predetermined area of said surface.
