Abstract
A switchgear assembly includes a vacuum interrupter assembly having an internal switching contact. A conductive current exchange is in electrical contact with the switching contact, and the current exchange defines an internal chamber within the current exchange. A plug of non-conductive, compliant material has a first portion that extends into the internal chamber in contact with the current exchange. An insulative encapsulation surrounds the vacuum interrupter assembly, the current exchange, and the plug.
