A ceramic insulator for vacuum interrupters extends along a longitudinal extent and forms a cavity in said longitudinal extent. The cavity has a first opening on a first end of the longitudinal extent and a second opening on a second end of the longitudinal extent. The openings are designed so that they can be sealed in a gas-tight manner using appropriate connections. The sealed first opening is designed to guide at least one fixed contact into the cavity, and the sealed second opening is designed to guide at least one moving contact into the cavity. The ceramic insulator has, on an inner face of the cavity, one or multiple electrically conductive discharge path interrupters extending perpendicularly to the longitudinal extent of the ceramic insulator.
