Abstract

A vacuum switch tube has a housing which has two insulating housing regions arranged and configured symmetrically in respect of a center plane. Each of the two insulating housings contains a plurality of insulating housing parts. Shielding elements extend into the interior of the vacuum switch tube and are arranged between neighboring insulating housing parts and between insulating housing parts and neighboring additional housing parts. The shielding elements have improved dielectric properties and a simultaneously material-saving structure. Accordingly, the geometrical dimensions of the shielding elements are determined in dependence on a connected voltage and possible critical field strength between neighboring shields.
