Abstract: A milling machine includes a frame, a milling chamber, a rotor, an enclosed operator cab. The frame has a first lateral side and a second lateral side. The first lateral side corresponds to a flush cut side of the milling machine. The milling chamber is supported by the frame and extends beyond the first lateral side in a lateral direction of the milling machine. The rotor is positioned within the milling chamber to grind a work surface. The enclosed operator cabin is mounted on the frame, and includes a seat for an operator of the milling machine disposed inside the enclosed operator cabin, and a viewing window that is positioned laterally outside the first lateral side of the frame. The viewing window is configured to provide a direct line of sight of the milling chamber to the operator seated on the seat.

Abstract: A method of manufacturing a capacitive electrical device is disclosed. The method includes a) bonding a first electrical insulation film with a second electrical insulation film to obtain a single electrical insulation film that has a larger surface area than any of the first electrical insulation film and the second electrical insulation film has alone, b) providing a conductive layer onto the single electrical insulation film, and c) winding the single electrical insulation film and the conductive layer around a shaft to obtain a layer of the single electrical insulation film and a layer of the conductive layer wound onto the shaft, thereby forming the capacitive electrical device.

Abstract: A rotor assembly includes a generally cylindrical rotor having a drive end and a bearing end opposite to the drive end. The rotor is rotatable about a longitudinal axis. The rotor assembly further includes a transmission contained substantially within the rotor at the drive end. The transmission has an input shaft and an output shaft offset from the input shaft. The output shaft is operatively coupled to the rotor and is coaxial with the longitudinal axis of the rotor. The rotor assembly further includes a bearing assembly contained substantially within the rotor at the bearing end. The rotor assembly has a mounting axis and a bearing axis offset from the mounting axis. The bearing assembly further has a rotatable bearing operatively coupled to the rotor and is coaxial with the longitudinal axis of the rotor.

Abstract: 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.

Abstract: The method relates to an electric device comprising at least two electrodes which are separated by dielectric part. At least one of said electrodes is arranged to be at a floating potential. The dielectric part comprises at least one turn of at least one non-impregnatable electrically insulating film between two neighboring electrodes. The electrodes are bonded to adjacent turns of non-impregnatable insulating film, and adjacent turns of non-impregnatable insulating film, if any, are bonded to each other, so that the turns of non-impregnatable insulating film and the electrodes form a solid body. The invention further relates to a method of manufacturing an electric device, where bonding of at least one turn is performed upon forming of said turn, so that the bonding of said turn to the turn/electrode underneath will commence before said turn has been completely covered by the next turn.

Abstract: A high-voltage bushing has a conductor and a core surrounding the conductor, wherein the core comprises a sheet-like spacer, which spacer is impregnated with an electrically insulating matrix material. The spacer is wound in spiral form around an axis, the axis being defined through the shape of the conductor. Thus, a multitude of neighboring layers is formed. The core further comprises equalization elements in appropriate radial distances to the axis. The equalization elements comprise electrically conductive layers, which layers have openings, through which openings the matrix material can penetrate, and in that the equalization elements are applied to the core separately from the spacer. The electrically conductive layers can be net-shaped, grid-shaped, meshed or perforated. The openings are fillable with the matrix material, e.g., a particle-filled resin can be used.

Abstract: An elongated member including an outer sleeve-like rigid insulator shell surrounding a high voltage conductor extending in the longitudinal direction of the shell and a gap inside the shell next to an internal wall of the shell at least partially surrounding the conductor and filled with a medium including a material of with electrically insulating properties. The medium is formed by an electrically insulating material including hollow spaces at least partially filled with gas. The material is adapted to expand upon a temperature rise thereof by reversibly compressing the hollow spaces and reducing the volume thereof.

Abstract: A bushing is disclosed with a duct for accommodating a conductor which is surrounded by an electrical field grading insulation. The bushing includes a core with a shell encapsulating the grading insulation and a flange surrounding the shell and carrying through holes distributed over its circumference for allowing the bushing to be attached to a wall. The shell and the flange can be in one piece and include an insulating matrix material. The through holes can be surrounded by metal inserts each forming an annular surface flush with a surface of the flange. A test tap can include a contact pin which is electrically conductively connected to an outermost layer of the grading insulation and surrounded by a contact ring connected to every second metal insert by connection wires for grounding the contact pin via the contact ring when the test tap is not in use and covered.
