Abstract
A high voltage bushing assembly includes an insulator shell adapted to enclose an electrical conductor. An annular flange is slidably received over the insulator shell, the annular sleeve formed with a radially outwardly directed flange at an upper end and a radially inwardly directed flange at a lower end, with a sleeve portion extending axially therebetween. The insulator shell has an outside diameter and the sleeve portion has an inside diameter sized to create an annular, radial gap therebetween filled with a high thermal endurance fiberglass-reinforced epoxy resin.
