BUSHING COMPRISING LOW-VISCOSITY INSULATING FLUID AND ELECTRICAL FACILITY WITH BUSHING
A bushing includes an insulating housing, an electrical conductor, extending through the housing and an insulating fluid in the housing, wherein the insulating fluid has a viscosity at a temperature of 100? C. of equal or less than 2 mm.sup.2/s. The bushing includes a condenser body surrounding the electrical conductor, wherein the condenser body includes electrically insulating layers and electrically conductive layers, wherein the electrically insulating layers are formed from a paper impregnated with the insulating fluid.

MOBILE TRANSFORMER BUSHING CONNECTION
An electrical device can be connected to a high-voltage power grid in a flexible and cost-effective manner. There is provided an apparatus with a housing that is filled with an insulating fluid. A high-voltage bushing has a high-voltage conductor that extends through a bushing insulator and is fastened to the housing. Furthermore, a cable connection is provided on the housing in order to connect a high-voltage cable. A connecting conductor which is surrounded by the insulating liquid establishes a direct electrical connection between the cable connection and the high-voltage conductor of the high-voltage bushing in the housing. The high-voltage bushing is therefore no longer inserted into a tank which is filled with oil, but rather is part of a mobile apparatus which is connected to a winding in the tank by way of a cable.
Electrical Bushing
An electrical bushing including an electrically insulating shell having a central longitudinal through hole and a first longitudinal end configured to be at a top of the bushing and a second longitudinal end configured to be at a bottom of the bushing. The bushing is configured for accommodating an electrical conductor positioned through the central longitudinal through hole of the shell. The shell includes fastening means for fastening the bushing to a wall of an electrical apparatus, through which wall the bushing is configured for allowing the electrical conductor to pass. The shell is configured forsealingly containing an electrically insulating liquid in the bushing, allowing the bushing to be liquid-filled. The shell is moulded as a single piece from an electrically insulating polymeric material.
