摘要： 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)

摘要： A high-voltage cable fitting (30) with a rigid core insulator (1) that has a first conical outer surface (4) extending concentrically about a longitudinal axis (5). An elastomeric stress relief element (6) has a first conical inner surface (7) is designed for mating the first conical outer surface (4) at an interface (9). A rigid member (11) is provided for pressurizing the elastomeric stress relief element (6) at the interface (9). The stress relief element (6) is pressed onto the rigid core insulator (1). The rigid member (11) has at least one pressure enhancing portion (17) extending circumferential about the longitudinal axis (5) for causing an additional axial expansion stress (23) in a sleeve portion (19) of the stress relief element (6) extending along the first conical outer surface (4) of the core insulator (1) in an assembled state of the cable fitting (30).
