Abstract
An interrupter unit includes a vacuum switch tube and an insulating housing. The insulating housing has an inner surface. The vacuum switch tube is bordered at least partially by an electrically insulating structure material having an outer surface. The insulating housing at least partially surrounds the vacuum switch tube. In operation, inner surface of the insulating housing and outer surface of the vacuum switch tube are separated by an adhesion layer. The inner surface and the outer surface are provided at least partially with an electrically conductive layer such that, in a boundary region between vacuum switch tube and insulating housing, the following layer sequence is directed radially outwards from a switch axis: structure material of vacuum switch tube; outer surface of structure material; conductive layer on outer surface of structure material; adhesion layer; conductive layer on insulating housing; inner surface of insulating housing; volume material of insulating housing.
