The gas-insulated cable (1) contains an insulating tube (2) which is filled with insulating gas, an electrical conductor (3) which is arranged in the insulating tube (2), carries high voltage and can be passed through an enclosure opening into the interior of metal encapsulation (5) which is filled with insulating gas, and a terminating piece (6). This terminating piece (6) is used for the connection for the metal encapsulation (5) and has a mounting flange (7) (which can be connected to a flange (11) of the metal encapsulation (5) in a gas-tight manner and is made of insulating material), as well as a rotationally symmetrical arc barrier (12) which extends from the mounting flange (7) into the tube interior. In order to achieve a dielectrically particularly effective termination of the gas-insulated cable (1), the arc barrier (12) is guided onto the outer surface of the electrical conductor (3) and has a shield (13) which rests on this outer surface.
Cette invention concerne un câble haute tension à isolant gazeux (1) qui comprend un tube isolant (2) rempli de gaz isolant et renfermant un conducteur électrique (3), ledit tube pouvant être inséré dans l'ouverture d'un boîtier métallique (5) également rempli de gaz isolant et équipé d'une pièce de raccordement (6). Cette pièce (6) sert au raccordement au boîtier métallique (5) et comprend une bride de montage (7) (qui peut être fixée à la bride de montage (11) du boîtier (5) de manière étanche et qui est en matériau isolant) ainsi qu'une barrière de coupure d'arc (12) de section circulaire symétrique qui fait le pont entre la bride de montage (7) l'intérieur du tube (2). Pour réaliser un raccordement à pouvoir isolant particulièrement élevé, la barrière de coupure d'arc (12) est centrée sur le conducteur électrique et comporte un écran (13) qui repose à la surface de celui-ci.
