Abstract:
A high-voltage cable joint for connecting terminus of conductors (4; 5) of a first (1) and a second (2) power cable, the conductors (4/5) of each of said cables (1/2) being surrounded by, successively, a first insulation layer (6/7), a semi-conductive layer (8/9), a metallic screen (10/11) and a second insulation layer (12/13),said cable joint including a junction body (3) having a first end and a second end and comprising connection means (14) for connecting together bared parts of the terminus of said conductors and insulation means (15; 16, 17) surrounding bared parts of the semi-conductive layer (8), of the first insulation layer (6) and of the conductor (4) of said first power cable (1), said connection means, and bared parts of the conductor (5), of the first insulation layer (7) and of the semi-conductive layer (9) of said second power cable (2),the metallic screen (10) of said first power cable (1) being electrically connected to a first end of a first metallic tubular shielding member (19) that covers said junction body (3), a second end of the first metallic shielding member overhanging beyond the second end of the junction body, an insulation sleeve (22) being provided between said junction body and said first shielding member (19), said insulation sleeve also having an end overhanging beyond said second end of the junction body, andthe metallic screen (11) of said second power cable (2) being electrically connected to a second end of a second metallic tubular shielding member (20), a first end of the second metallic tubular shielding member abutting against said second end of said junction body (3), said first end of said second shielding member being partially engaged underneath the hanging end of said insulation sleeve (22) as well as under the second end of said first shielding member (19) without having an electrical contact therewith,characterized in that an insulation ring (23) is provided with a tight fit over at least the first end of second metallic tubular shielding member (20),in that said insulation ring (23) has at least a first end that is engaged underneath the hanging end of said insulation sleeve (22), andin that pressing means (24) are provided to press said hanging end of said insulating sleeve (22) against the first end of said insulation ring (23).
