A high-voltage cable joint for interconnecting terminus of conductors (4; 5) of a first (1) and a second (2) power cable, each cable having a metallic screen (10; 11) separated from the conductor by an insulation layer (6; 7) and a semi conductive layer (8/9). The cable joint includes a junction body (3) that is an insulated box wherein the conductors are interconnected. The metallic screen (10) of the first power cable (1) is electrically connected to one end of a first metallic tubular shielding member (19) of which the other end extends beyond the junction body. This member (19) is separated from the junction body by an insulation shield-break sleeve (22) and both have an end overhanging beyond the end of the junction body. The metallic screen (11) of the second power cable (2) is electrically connected to an end of a second tubular shielding member (20) that is a rigid tube of which the other end abuts against the end of the junction body (3) and is partially engaged underneath the end of the shield-break sleeve (22) and thus also of the first tubular shielding member (19) without having an electrical contact therewith. An insulation ring (23) is provided at the end of the second shielding member (20). This ring has a recessed part that is engaged, with a tight fit, underneath the end of the insulation sleeve (22). Preferably the insulation sleeve (22) is further pressed against the insulation ring (2). In this way, a relatively cheap, light and easy to handle cable joint with good water impervious shield-break is provided.
