Abstract: The subject of the invention is a conductive screen for power electronic elements enclosed in insulating medium and working on high voltage potential having an application in energetic industry, specially designed for HV transformer. Conductive is characterized in that the power electronic element (1) is electrically connected with a heat radiator (8) having an external surface (8a) and a first conductive screen (10) is placed on the surface (8a) of the radiator (8). The first conductive screen is electrically connected with high voltage potential derived through a HV terminal (3). The conductive screen is adapted for shaping an electric field distribution between the potential of the screen (10) and a ground potential of the housing (5) filled-in with the insulating medium (6). The screen (10) is attached to the flat surface (8a) of the heat radiator (8) in such a way that the sharp edges of the radiator (8) and the power electronic device (1) are encircled by the screen (10) and a second conductive screen (10') is placed in the insulating medium (6) and the second screen (10') is electrically connected with the first screen (10).

Abstract: A high-voltage cable fitting, typically a cable end termination or a cable joint, comprises coaxially arranged around an axis (A) a rigid conical insulator, an electrically insulating, elastomeric stress-relief cone (20) matching the rigid conical insulator through a conical interface (30) and an axially aligned current path. The current path connects a conductor (42) of the cable (40) to a high-voltage current terminal (43) 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 (10) and comprises a plurality of electrically conductive field-grading layers (13a, 13b, 13c), which are arranged concentrically around the axis (A), and a rigid polymeric matrix (14) 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 (41) of the cable conductor (42), which is stripped off the insulation (44) of the cable (40), extends from the conical interface (30) to the high-voltage current terminal (43) and forms the axially aligned current path, and the condenser core (10) comprises an axially aligned tubular duct (11) which receives the stripped-off section (41) of the cable conductor (42) and which passes two opposing front faces (12a, 12b) of the condenser core (10).
