A power device includes a gas chamber adapted to include an insulation gas under a set of use conditions including a predetermined installation pressure, and an insulation component including a material in which said insulation gas is soluble and being arranged in relation to said gas chamber so as to be at least partly exposed to said insulation gas when the power device is in said use state. The power device has a delivery state, being a state of said power device before and/or at an installation time at which the power device is installed in said electric energy power arrangement under said set of use conditions including said installation pressure of said insulation gas in said gas chamber, wherein, in said delivery state, said insulation component includes an amount of pre-filled insulation gas which is dissolved in the material of the insulation component.

Power device comprising an insulation gas for use in an electric energy power arrangement

The disclosure relates to an adaptation module configured for connecting three conductors of two modules and/or bays of a three-phase encapsulated gas-insulated switchgear, including two opposite arranged insulators each including three radially spaced conductor connection inlets and configured for electrically connecting the conductor connection inlets to one of the two modules and/or bays, and three concentrically arranged axially extending conductors each connected to two opposite conductor connection inlets, spaced from each other and rotatable in respect to the axis.

Adaptation module for a gas-insulated switchgear

A switch including a housing, a first contact arrangement having a first commutation contact element and a first contact, a second contact arrangement having a second commutation contact element and a second contact, and also a nominal contact arrangement. The first commutation contact element and the second commutation contact element form a snap-action connection with one another in the closed position of the commutation contact element. When the switch is closed, a distance between the first contact and the second contact is smaller than a distance between the first commutation contact element and the second commutation contact element in the direction of the axis.
