Abstract: Sleeve (1) for a high- or medium-voltage power cable (120) having an inner conductor (130). The sleeve comprises (i) a tubular sleeve body (10) having an electrically conductive or semiconductive first axial electrode section (60), and (ii) a circuit board (30). The sleeve is radially expandable or shrinkable. It can be arranged radially outward of the inner conductor, such hat the first axial electrode section is radially separated from the inner conductor by at least an electrically insulating spacer layer (140). The circuit board is at least partially arranged radially outward of the sleeve body and comprises an electrical contact (100) which is electrically connected with the first axial electrode section.

Abstract: Terminal connection device (10) for connecting an end of a medium- or high-voltage power cable (42) to a connection point, the terminal connection device (10) comprising an interface cable (12) having first and second end portions, comprising an inner conductor (14) and a conductive or semiconductive layer (18). The terminal connection device further comprises a first stress control tube (36) comprising—a stress control element (38), and an insulating layer (40) arranged around the stress control element (38), wherein the first stress control tube (36) is mounted on the first end portion of the interface cable (12).

Abstract: Electrical stress control device for use with an end portion of a cable (1) having a central conductor (5) and a ground layer (15), the stress control device comprising an axial bore (170) into which the end portion of the cable (1) can be inserted, and two or more conductive or semiconductive stress control layers (110, 120, 130), at least parts of which are arranged concentrically around the bore (170) and concentrically with each other, characterized in that the end portion of the cable (1) can be inserted into the bore (170) in an axial direction (25) in such a way that the stress control layers (110, 120, 130) of the stress control device extend, in said axial direction (25), further towards the end (3) of the cable (1), than the ground layer (15) of the cable (1), as viewed in an axial longitudinal section, and in that a radially outer one of the stress control layers (110, 120, 130) extends, in said axial direction (25), further towards the end (3) of the cable (1) than a radially inner one of the stre
