  • Patent number: 8969729
    Abstract: A high-voltage bushing with conductive inserts for a DC voltage has a bushing body surrounding a high-voltage conductor and containing a paper insulation. The bushing body tapers conically, at least at one end region thereof, from a ground-potential-side location to a high-voltage-side end and is surrounded by an insulating barrier. In order to provide a high-voltage bushing of this type with a particularly good potential distribution, the outside of the bushing body is coated at least in the region of the at least one end region with a coating to form a coating layer, which has a greater electrical conductivity than the bushing body.

  • Patent number: 8129629
    Abstract: An arrangement for reducing the electric field strength on the face of an electrode, wherein the face of the electrode is surrounded by at least one electric barrier, and a shielding electrode having a defined voltage potential is disposed in the vicinity of the face of the electrode. By using a retaining element that can be connected directly to the face of the electrode, the shielding wires can be quickly and easily positioned and fixed relative to the face of the electrode and the shielding electrode relative to the face.

  • Patent number: 8124878
    Abstract: An apparatus for electrical screening of a bushing output of a high-voltage line into an outer wall of an electrical high-voltage device, includes an electrically conductive screen interior and an outer insulation layer, which surrounds the screen interior. A curved circular segment with two limbs in conjunction with a correspondingly shaped barrier system ensures virtually complete electrical screening of corners and edges of a bushing output.

  • Patent number: 7952031
    Abstract: A barrier system for a line leadthrough in an electric installation has mutually adjacent wall elements forming barriers that extend in an axial longitudinal direction and are spaced apart from each other, forming channels. The wall elements lie partially on a support, at least at their lower ends. The wall elements are joined by a plug element to the leadthrough. Slots having a width which corresponds to the wall thickness of the wall elements are arranged in the plug element. The wall elements can be inserted into the slots, thus permitting a barrier system to be quickly and easily assembled and disassembled.

  • Patent number: 7927141
    Abstract: An electrical shielding arrangement of a high-voltage line has at least two coupling elements. The coupling elements each have a tubular control electrode about a line leadthrough and are surrounded by a barrier. Owing to the fact that the reduction in the diameters of the control electrode and the barrier is matched in relation to one another, a barrier decoupled in this way can be used for mechanically tensioning the coupling systems which have been pushed one inside the other.
