Abstract: A switch for a medium voltage or high voltage switchgear includes: a first fixed contact; a second fixed contact; a moveable contact; at least one flexible link; and a contact drive. In an on state of the switch, the moveable contact is in a position that connects the first fixed contact to the second fixed contact. In an off state of the switch, the moveable contact is in a position where the first fixed contact is not connected to the second fixed contact. The at least one flexible link is connected to the moveable contact. The at least one flexible link engages with the contact drive. The contact drive pulls the moveable contact via the at least one flexible link and pushes the moveable contact via the at least one flexible link. Activation of the contact drive in a first mode moves the moveable contact.

Abstract: A cable fixation element for low voltage compartments includes an openable ring element, through which a number of cables can be aligned in parallel, the cable fixation element having a fixing unit by which the cable fixation element can be fixed on a cable mounting board. The ring is openable such that a physical opening direction is parallel to a long axis of the cables, which have to be placed in the cable fixation element. A frame structure of the cable fixation element is provided at all sides of the frame in double layer, except of the top side, where c-structured portions are implemented.

Abstract: A cooling system for a medium voltage switchgear includes a conductor, a fluid conduit, and an insulator, wherein, the conductor extends in a longitudinal axis, wherein, the conductor is configured to carry electrical current in the longitudinal axis direction, wherein a first part of the fluid conduit is located around an outer surface of the conductor and extends around the longitudinal axis, wherein, a second part of the fluid conduit is connected to the first part of the fluid conduit and extends substantially perpendicularly to the longitudinal axis, wherein the insulator is located around the conductor at the position of the fluid conduit and covers the first part of the fluid conduit, and wherein the cooling system is configured such that a fluid can flow into the second part of the fluid conduit and from the second part of the fluid conduit into the first part of the fluid conduit.

Abstract: A rotary auxiliary switch for medium voltage switchgears, has a lever with a cam track, along which a driving element is movable. In order to cause the lever to be covered in such a way, the operator cannot touch the application, such that the lever is split into two complementarily lever components the two components creating a hinge, when they are mechanically mounted, the resulting cam track also being splitted into two cam track parts, such that a partly first cam track is located in the first lever component, and the partly second cam track is located in the second lever component.
