Patent ID: 8492656

Claim:
A high voltage bushing flange assembly comprising: an insulator shell adapted to enclose an electrical conductor; an annular bushing flange slidably received over said insulator shell, said annular bushing flange 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; said insulator shell having an outside diameter and said sleeve portion having an inside diameter sized to create an annular, radial gap between said insulator shell and said sleeve portion, said radial gap filled with a high thermal endurance fiberglass-reinforced epoxy resin, supported axially by said radially inwardly directed flange; wherein said insulator shell is formed to include at least one annular radially outwardly-extending rib radially overlapping said radially inwardly directed flange; and wherein an annular seal is seated on said radially inwardly-directed flange and axially compressed between said at least one annular, radially outwardly-extending rib and said radially inwardly-directed flange.
