Title
(EN) REPAIR AND REPLACEMENT OF HIGH VOLTAGE CABLES AND JOINTS
(FR) RÉPARATION ET REMPLACEMENT DE CÂBLES ET DE JOINTS À HAUTE TENSION
Abstract
(EN)
A method of repairing or replacing a joint for high voltage polymer cables or a high voltage polymer cable (1c), comprises the steps of: a) removing a section to be replaced of the joint or the high voltage polymer cable (1c) such that two cable ends (1a,1b) result, whereby the two cable ends (1a,1b) are oriented toward each other and whereby the two cable ends (1a,1b) are positioned in a separation distance (20) from each other and whereby each cable end (1a,1b) comprises a cable conductor (10a,10b), b) preparing the two cable ends (1a, 1b) by exposing the cable conductors (10a, 10b) of both cable ends (1a,1b) over a first length c) connecting the two cable conductors (10a, 10b) with a connection piece (3) which comprises two receiving sections (31a, 31b) and a centre section (30) and which is electrically conducting, whereby a length of the centre section (30d) corresponds to the separation distance (20) and whereby the cable conductors (10a, 10b) are mounted in such a way to the receiving sections (31a, 31b) that a mechanical and an electrically conducting connection is established.

La présente invention concerne un procédé de réparation ou de remplacement d'un joint pour câbles polymères haute tension ou d'un câble polymère haute tension (1c), et comprend les étapes consistant à : a) retirer une section à remplacer du joint ou du câble polymère haute tension (1c) de sorte que deux extrémités de câble (1a, 1b) en résultent, les deux extrémités de câble (1a, 1b) étant orientées l'une vers l'autre et les deux extrémités de câble (1a, 1b) étant positionnées à une distance de séparation (20) l'une de l'autre et chaque extrémité de câble (1a, 1b) comprenant un conducteur de câble (10a, 10b), b) préparer les deux extrémités de câble (1a, 1b) en exposant les conducteurs de câble (10a, 10b) des deux extrémités de câble (1a, 1b) sur une première longueur c) relier les deux conducteurs de câble (10a, 10b) à une pièce de connexion (3) qui comprend deux sections de réception (31a, 31b) et une section centrale (30) et qui est électriquement conductrice, une longueur de la section centrale (30d) correspondant à la distance de séparation (20) et moyennant quoi les conducteurs de câble (10a, 10b) sont montés de telle manière aux sections de réception (31a, 31b) qu'une connexion mécanique et électriquement conductrice est établie.
