Abstract: The present invention relates to an electrical device comprising a gas-insulated transformer or reactor. The electrical device comprises a housing enclosing an interior space, at least a portion of which defining an insulation space containing a dielectric insulation fluid comprising an organofluorine compound, and an electrical component being arranged in the insulation space and being surrounded by the insulation fluid. The electrical component comprises at least one winding. The electrical device further comprises an electrical connector for bringing the apparatus from non-operational state to operational state by connecting at least one winding to a power grid. The device further comprises an auxiliary power source which is connectable to at least one winding when the apparatus is in the non-operational state.

Abstract: An electrical transformer includes a coil pack including windings, and spacers axially spacing turns of the windings from one another and being formed of a thermoplastic material. Sticks couple and position the spacers. The coil pack has high resistivity to creep and permits temperature rise without degradation of transformer insulation, providing for extended service life and unique methods of transformer system upgrade.

Abstract: The present invention relates to gas-insulated electrical apparatuses, in particular gas-insulated transformers or reactors, comprising a housing enclosing an interior space, in which an electrical component comprising a winding is arranged, at least a portion of the interior space defining an insulation space which is filled with an insulation fluid electrically insulating at least a part of the electrical component from the housing. According to the invention, the electrical apparatus further comprises a cooling element comprising a condenser, an evaporator and a cooling fluid to be circulated between the condenser and the evaporator. The evaporator is designed such that at least a part of the electric component is immersed in the cooling fluid in its liquid state, thus being in direct contact with the cooling fluid.

Abstract: A method of manufacturing a polymer-insulated conductor. The method includes the steps of a) providing a conductor having a first cross-sectional shape, b) passing the conductor through a conductor-shaping die to shape the conductor such that the conductor obtains a second cross-sectional shape, wherein frictional heat is developed in the conductor, thereby setting the conductor in a heated state, c) applying molten polymer to the conductor when the conductor is in the heated state to obtain a polymer-coated conductor, and d) shaping the polymer-coated conductor by means of a polymer-shaping die to thereby obtain the polymer-insulated conductor.
