Various embodiments include a method for producing a ceramic insulator for a high-voltage or medium-voltage switching system comprising: attaching a base material for an equipotential layer between two axially symmetrical ceramic structural elements; disposing the electrically conductive equipotential layer between the two ceramic structural elements; and joining the two ceramic structural elements to form a unitary body along a symmetry axis of a first of the two elements.

Ceramic insulator

A vacuum circuit breaker includes a vacuum circuit breaker tube having a vacuum housing in which a contact system is disposed. The contact system includes two contacts which are movable relative to one another. An electrical pre-arcing unit having an ignition electrode in the vacuum housing is provided for igniting an arc along an arc current path.
