A terminal connection device for connecting an end of a medium- or high-voltage power cable to a connection point comprises 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; and 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.

Terminal connection device for a power cable

Sensored cable () for distribution of electrical power in a power network, the sensored cable comprising an inner conductor and an insulating layer () arranged concentrically around at least an axial section of the inner conductor. The sensored cable further comprises a capacitive voltage sensor () for sensing a voltage of the inner conductor, characterized by the sensor including a printed circuit board element (), which is placed over an electrically isolated piece () of conductive or semiconductive material, arranged on the insulating layer of the cable. The electrically isolated piece () of conductive or semiconductive material is operable to form an electrode of a sensing capacitor of the capacitive voltage sensor. The cable may comprise a (semi-) conductive layer (). The electrically isolated piece () of conductive or semiconductive material may comprise a portion of the (semi-) conductive layer.
