ABSTRACT:
An electric switchboard for medium voltages provides for the insulation of the compartments by means of sulfur hexafluoride gas, and each compartment is subdivided into superimposed cells which are metallically separated from one another and are gastight. In the cells auxiliary isolators are also provided for electrically isolating parts of the compartment for the purpose of maintenance without putting the entire switchboard out of action.
