Terminal connection device for a power cable

Terminal connection device for connecting an end of a medium- or high-voltage power cable to a connection point, the terminal connection device comprising:

• a) an interface cable having first and second end portions, comprising an inner conductor and a conductive or semiconductive layer,
• b) a first stress control tube comprising
• a stress control element, and
• an insulating layer arranged around the stress control element,
• wherein the first stress control tube is mounted on the first end portion of the interface cable;
• c) a first cable connector for connecting the interface cable to the power cable,
• the first cable connector being connected to the second end portion of the interface cable;
• d) one or more tubular shrinkable sleeves,
• at least a portion of one of the tubular shrinkable sleeves extending over at least a portion of the first stress control tube,
• wherein the portion of the tubular shrinkable sleeve extending over at least a portion of the first stress control tube is shrunk down around at least a portion of the first stress control tube, wherein the interface cable further comprises an insulating layer arranged concentrically around at least an axial section of the inner conductor,
• and wherein the terminal connection device comprises a capacitive voltage sensor including a printed circuit board element, the printed circuit board element placed over an electrically isolated piece of conductive or semiconductive material, the electrically isolated piece of conductive or semiconductive material arranged on the insulating layer of the interface cable and operable to form an electrode of a sensing capacitor for sensing a voltage of the inner conductor, and wherein the insulating layer is operable to form a dielectric of the sensing capacitor.
