Abstract

A vacuum interrupter tube contains at least one insulating body, a fixed contact, a fixed contact flange, a moving contact having a longitudinal axis, a moving contact flange, and a bellows. The fixed contact is stationarily arranged in the fixed contact flange. The moving contact is moveably guided and the moving contact is moveably secured to the moving contact flange by the bellows. The bellows is secured to the moving contact flange by a first bellows end and the bellows is secured to the moving contact by a second bellows end. Therein the vacuum interrupter tube is protected against the deformation of at least one of the fixed contact flange and the moving contact flange due to an ambient pressure of the vacuum interrupter tube of over two bar by a stiffened fixed contact flange and/or a stiffened moving contact flange.
