Title (EN) JOINT FOR HIGH VOLTAGE DIRECT CURRENT CABLES
(FR) JONCTION POUR CÂBLES À COURANT CONTINU À HAUTE TENSION
Abstract:
(EN) The present invention relates to a joint (100) for high voltage direct current cables (200, 300) extending 5 along a longitudinal axis (X) between two opposite end portions (110, 120), the joint (100) comprising: - a central semiconducting electrode (140); - two semiconducting deflectors (150, 160); - a field grading layer (170) longitudinally extending 10 between each one of the deflectors (150, 160) and the central electrode (140) and in electric contact therewith; - a joint insulating layer (180) surrounding the central electrode (140), the two deflectors (150, 160) 15 and the field grading layer (170); and - a joint outer semiconductive layer (190) surrounding and in direct contact with the insulating layer (180).
(FR) La présente invention porte sur une jonction (100) pour des câbles (200, 300) à courant continu à haute tension s’étendant le long d’un axe longitudinal (X) entre deux parties d’extrémité (110, 120) opposées, la jonction (100) comprenant : - une électrode centrale (140) semi-conductrice ; - deux déflecteurs (150, 160) semi-conducteurs ; - une couche de graduation de champ (170) s’étendant longitudinalement entre chacun des déflecteurs (150, 160) et l’électrode centrale (140) et en contact électrique avec eux ; - une couche isolante (180) de jonction entourant l’électrode centrale (140), les deux déflecteurs (150, 160), et la couche de graduation de champ (170) ; et - une couche extérieure (190) semi-conductrice de jonction entourant en contact direct la couche isolante (180).
