Abstract

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.
