A gas-insulated puffer-type switch device for operating inside a sealed gas tight enclosure of an electric power distribution switchgear, the sealed gas tight enclosure being filled with a dielectric gas having a global warming potential lower than that of SF6. The switch device has at least one of improved compactness, minimised electrical stress, maximised heat dissipation and reduced environmental impact.

Switch device

A switching device for an encapsulated electric power distribution switchgear and an electric power distribution switchgear with at least one such switching device are disclosed. The switching device has a first electrically conducting housing which encloses an actuator mechanism for a first contact assembly and a second electrically conducting housing which encloses a second contact assembly. The first electrically conducting housing is arranged at a distance from the second electrically conducting housing. The switching device further has a third housing which is electrically insulating and arranged between the first electrically conducting housing and the second electrically conducting housing. The switching device is a puffer type switch.

Housing for electrical breaker

An apparatus, such as a metering panel, for electric power distribution. An enclosure having an access opening defining an interior space, at least two electrical components for separate phases of electricity. The two components located within the enclosure and spaced laterally apart, at least one electrically insulating barrier panel, movable between at least two guided positions, a working position within the enclosure and between the components and an access position displaced from the components.
