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.

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.
A high voltage bushing 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 thereof and an axially-oriented sleeve portion, said insulator shell having a substantially uniform outside diameter and said sleeve portion having a substantially conically-shaped inside surface sized to create an annular, conically-shaped radial gap between said insulator shell and said axially-oriented sleeve portion, said conically-shaped radial gap filled with a high thermal endurance fiberglass-reinforced epoxy resin.
A bushing assembly comprising:
- a substantially cylindrical shell;
- an annular bushing flange slidably received over said substantially cylindrical shell, said annular bushing flange formed with a radially outwardly directed flange at one end and a radially inwardly directed flange at an opposite end, with a sleeve portion extending axially therebetween;
- said substantially cylindrical shell having an outside surface and said sleeve portion having an inside surface sized to create an annular radial gap therebetween, said radial gap filled with a high thermal endurance fiberglass-reinforced epoxy resin between said radially outwardly directed flange and said radially inwardly directed flange, bonding said bushing flange to said substantially cylindrical shell.
