The present disclosure relates to a high-voltage (HV) bushing comprising a condenser core configured for surrounding a HV electrical conductor. The condenser core comprises an insulation material comprising wound layers of a permeable solid material impregnated with a thermo-reversible gel. The gel comprises an oil and a thickener, the oil comprising iso-paraffinic oil in an amount within the range of 0.1-100 wt % of the oil and the thickener comprising at least one copolymer in an amount within the range of 0.1-10 wt % of the gel.

Gel impregnated bushing

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.

Electrical device comprising a gas-insulated apparatus, in particular a gas-insulated transformer or reactor

A pressure compensated subsea arrangement for housing of electric components. The arrangement includes a pressure compensated housing. The pressure compensated housing is filled with a dielectric liquid. The arrangement includes at least one electric component. The at least one electric component is provided inside the pressure compensated housing. The dielectric liquid is a hydrocarbon dielectric liquid including isoparaffin. There is also provided a method of manufacturing such an arrangement.

The present invention relates to a liquid composition for electrical insulation including a dielectric fluid and an additive, the additive being dissolved in the dielectric fluid and having a 1excitation energy which is lower than the 1excitation energy of the dielectric fluid.

Dielectric fluids having reduced streamer speed

Electrical equipment including insulating fluid and having isoparaffins derived from a renewable carbon source, the fluid having a flash point of at least 210&#xb0; C. and comprising at least 70 wt % of the isoparaffins. The electrical equipment can be installed and operated subsea.

Renewable hydrocarbon based insulating fluid

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.
