Abstract: A high-voltage device has an encapsulation housing and at least one bushing for at least one electrical conductor leading into the encapsulation housing and/or leading out of the encapsulation housing. The at least one electrical conductor is coated with an insulation layer. The insulation layer increases the dielectric strength in the high-voltage device, in particular in the region of the bushing.

Abstract: A conductor assembly includes an electrical conductor, a surge arrester which has a longitudinal direction, an operating state in which the surge arrester is configured to limit an overvoltage occurring in the electrical conductor, and a test state in which the surge arrester is not configured to limit the overvoltage. An electrically insulating support is disposed between the surge arrester and the electrical conductor in the longitudinal direction. The support is supported by the electrical conductor, and the surge arrester is supported by the support.

Abstract: A high-voltage device has an encapsulation housing and at least one bushing for at least one conductor, through which a current flows, into the encapsulation housing and/or out of the encapsulation housing. At least one electrode at free potential is surrounded by the bushing. The at least one electrode at free potential increases the dielectric strength in the high-voltage device, especially in the region of the bushing.

Abstract: A high-voltage power switch, preferably with a dead tank design, contains: a switching unit that has a switching device and an actuation element that is axially movable in relation to a longitudinal axis of the switching device to actuate the switching device and a closing resistor unit that has a closing resistor arrangement and an adjusting element that is axially movable in relation to a longitudinal axis of this closing resistor arrangement to actuate the closing resistor arrangement. The actuation element is coupled to the adjusting element in order to move the latter. Accordingly, the longitudinal axis of the switching unit and the longitudinal axis of the closing resistor unit are spaced apart, and the actuation and adjusting elements are coupled by a coupling device of the high-voltage power switch.
