Abstract
A high voltage bushing includes an electrically conductive coupling having an aperture; first and second dielectric tubes mounted to the coupling so that they are coaxially aligned and have first and second ends, respectively, first and second end plates mounted in a fluid tight manner to the first and second ends of the first and second tubes, respectively; an electrically conductive ground shield mounted in the aperture, and having an inwardly profiled end for moderating an electric field along the bushing, and having second and third apertures; and a center conductor that extends through the second and third apertures of the ground shield, and is mounted to the first and second end plates.
