Single phase or polyphase switchgear comprises one or more switches which are mounted with the aid of solid insulation such that they are insulated, as well as associated live components such as rail systems and connectors, wherein both the switches and the associated live components are housed in a housing enveloping (7) the switches and live components, in which the enveloping housing is filled with air having a low moisture content and the interior space thereof is sealed with respect to the exterior space around the enveloping housing in such a way that the air present in the housing is not contaminated and will not reach the dew point, characterised in that a moisture-absorbent agent (33) is arranged in the enveloping housing (7), the quantity of the moisture-absorbent agent (33) being such that the moisture that penetrates as a result of leakage of the enveloping housing (7) is absorbed during the life of the switchgear.
