Abstract

Terminal connection device for connecting an end of a medium- or high-voltage power cable to a connection point, comprising an interface cable, an inner conductor and a conductive or semiconductive layer. The terminal connection device further comprises a first stress control tube comprising a stress control element and an insulation layer arranged around the stress control element. The terminal connection device further comprises a first cable connector for connecting the interface cable to the power cable. The terminal connection device further comprises a second stress control tube comprising a stress control element and an insulating layer arranged around the stress control element, wherein the second stress control tube is mounted over the second end portion of the interface cable and at least a portion of the first cable connector. The terminal connection device further comprises one or more tubular shrinkable sleeves.
