Abstract
The invention relates to enclosures () for gas-insulated medium-voltage or high voltage apparatuses. A connection portion () between a first end () of the first enclosure tube () and a mating machined second end () of the second enclosure tube () has a gas-escape path (L) running from the inside () to the outside () of the enclosure tubes (). According to the invention, the gas-escape path (L) is shaped to have a first segment (L) running along an at least partially axial direction of the enclosure () and being equipped with least one sealing ring (). In addition, a slim ring-like snap-on bracket () can be used. The direct machining of the mating enclosure ends () allows to omit conventional flanges. The partially axial orientation of the gas-escape path (L) allows to provide plural sealing rings () in series in the gas-escape path (L).
