A switching device including a breaker electrically connectable to an electrical conductor, and an at least partially electrically conductive housing to which the breaker is mounted, the housing having an outer surface. The breaker includes an electrically conductive first contact and an electrically conductive second contact, the second contact being movable and in relation to the first contact and in relation to the housing, and when the first and second contacts are in contact the breaker is in a closed position, and when the first and second contacts are separated the breaker is in an open position. The switching device is arranged to provide a current path between the breaker and the electrical conductor, and the housing houses a guiding member for operating the second contact, the guiding member being movable in relation to the housing, wherein the guiding member includes a biasing assembly.

Housing for electrical breaker

A switch device including a bus bar, and a switch knife, wherein the knife is arranged so as to pivot around an axis perpendicular to a longitudinal axis of the bus bar. The bus bar presents a projection which is an integrated part of the bus bar, and the knife is pivotable to a first position, in which it directly contacts said projection, and to a second position in which it is removed from contact with said projection.

Equipment for electrical power distribution

Housing for electrical connectors

A device for electric connection to an energy supply conductor for medium and/or high voltage having a voltage-carrying element with an outer periphery, and a tubular outer shell with an inner periphery, the outer shell being formed by a polymer, and along at least a part of the axial extension of the element the outer shell extends axially with a space between its inner periphery and the outer periphery of the element, at least along a section of said part of the axial extension of the element the space is filled with a filler of an electrically insulating material other than that of the outer shell. An electric installation including the device, and a method for producing the device.

Device for electric connection, a method for producing such a device, and an electric installation

An electric power distribution arrangement having an electric conductor for carrying a high voltage, a first pair of bodies provided on opposite sides of the conductor as seen in a first direction cross-wise to a longitudinal axis of the conductor, and a second pair of bodies provided on opposite sides of the conductor as seen in a second direction cross-wise to the longitudinal axis. The bodies of the first and second pair of bodies are arranged to be electrically disconnected from the conductor, and the spacing between the bodies of the first pair is larger than the spacing between the bodies of the second pair. At least one of the bodies of at least one of the first and second pair comprises a second current conductor, and at least one of the bodies of at least one of the first and second pair comprises a wall element of an encapsulation inside which the conductor is arranged. In a region in which the conductor is surrounded by the first pair and second pair, the conductor has a substantially oval or substantially elliptical shaped outer periphery, and the cross section of the conductor has a larger dimension in the first direction than in the second direction.

Electric power distribution arrangement and a switchgear provided therewith

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.

Apparatus for electric power distribution

A device for electric connection to an energy supply conductor for medium and high voltage, including: a voltage-carrying element; a tubular outer shell formed by a thermoplastic polymer and connected to the voltage carrying element; wherein the voltage-carrying element extends in a longitudinal direction of the tubular shell, and wherein, at least along a part of the length of the voltage-carrying element, the outer shell extends in a longitudinal direction with a space between its inner periphery and an outer periphery of the voltage-carrying element; the outer shell being provided with an outer contact surface to be connected to a wall of a gas-tight container somewhere along the part of the length of the voltage-carrying element; wherein the outer shell is arranged so as to separate said space from an atmosphere outside a container to which the device may be connected. At least along a section of the part of the length of the voltage-carrying element the space is filled with a filler of an electrically insulating material other than that of the outer shell, the filler completely filling the space along the section.
