Abstract
A stress control apparatus for managing effects caused by electrical stress in a high voltage environment, and methods of manufacturing the apparatus. A dielectric tube with a central bore coated with a conductive material has an outer conductive coating on a lower section that is grounded. The central bore carries a high voltage potential from a current-carrying conductor. The grounded coating transitions to the exposed outer dielectric surface along a gradually tapered transition. A conductive insert connects to the central bore and forms an electric field in a space between the insert and the grounded coating. When coated with an epoxy and inserted into the central bore, the insert forms a small gap between an outer surface of the insert and part of the central bore, such that there is no zero potential difference in the gap. Any epoxy that oozes out during insertion will collect in the gap.
