An encapsulated, gas-insulated electrical switch panel which is constructed from compartmentalised housings has pressure relief devices in each case for the housings. In the case of the invention, the housing wall is folded up immediately by the overpressure. This is achieved by incomplete cutting through the housing wall, in the form of a line, along a relief opening. Webs which tear away in an objective manner remain between the cuts. The cuts are covered in a gas-tight manner on the inside of the housing by a bonded-on metal film. |
