Abstract: The method is provided for manufacturing a perforated sheet-like high-voltage insulating spacer for a high-voltage component, which component comprises a field grading condenser core with the spacer which is wound in spiral form around an axis, with electrically conducting layers which are inserted between successive windings of the spacer, and with a polymeric matrix which penetrates the spacer and which embeds the spacer and the layers. The method comprises at least steps as follows: an electrically insulating tape, and the patterned tape is expanded at right angle to the cutting lines in order to form a spacer with a perforated three-dimensional lattice structure. The combined effect of cutting a tape and expanding the cutted tape allows the formation of spacers with a manifold of sizes which exceed the size of the tape in function of manufacturing parameters, in particular in function of the configuration of the pattern and the magnitude of the expansion.

Abstract: A high-voltage cable fitting, typically a cable end termination or a cable joint, includes coaxially arranged around an axis a rigid conical insulator, an electrically insulating, elastomeric stress-relief cone matching the rigid conical insulator through a conical interface and an axially aligned current path. The current path connects a conductor of the cable to a high-voltage current terminal arranged on top of the rigid conical insulator and provided for connection to a high-voltage component. The rigid conical insulator is configured as a condenser core and includes a plurality of electrically conductive field-grading layers, which are arranged concentrically around the axis, and a rigid polymeric matrix which embeds the field-grading layers. In order to keep the size of the cable fitting small and to enable the fitting to carry high rated continuous currents a section of the cable conductor, which is stripped off the insulation of the cable, extends from the conical interface to the high-voltage current terminal and forms the axially aligned current path, and the condenser core comprises an axially aligned tubular duct which receives the stripped-off section of the cable conductor and which passes two opposing front faces of the condenser core.

Abstract: A high-voltage cable fitting with a rigid core insulator that has a first conical outer surface extending concentrically about a longitudinal axis. An elastomeric stress relief element has a first conical inner surface is designed for mating the first conical outer surface at an interface. A rigid member is provided for pressurizing the elastomeric stress relief element at the interface. The stress relief element is pressed onto the rigid core insulator. The rigid member has at least one pressure enhancing portion extending circumferential about the longitudinal axis for causing an additional axial expansion stress in a sleeve portion of the stress relief element extending along the first conical outer surface of the core insulator in an assembled state of the cable fitting.

Abstract: The present invention refers to HV apparatus, in particular a HV dry current transformer, insulated with an insulating gel, or a voltage transformer, insulated with an insulating gel. The dry HV current transformer comprises at least two electrically conductive elements i.e. a head transformer cover, a head housing base, a core casing and a primary conductor. In the dry HV current transformer at least one of the electrically conductive elements has a coating made of solid insulating material separating the surface of the conductive elements from the insulating gel and adapted for limiting the electron emission from the conductive elements into the insulating gel. The voltage transformer comprises a bottom external housing, a bottom support flange, a core. In the voltage transformer at least one of the electrically conductive elements has a coating made of solid insulating material separating the surface of the conductive elements from the insulating gel and adapted for limiting the electron emission from the conductive elements into the insulating gel.
