Abstract: front page image
(EN)A gas-filled cable having low heat emission and low power loss and being used for the transmission of high-voltage electric current. The cable includes one or more conductors (14) which are axially spaced in position relative to each other in the cable by means of supporting insulators (16) inside an enclosing conduit (10, 12 or 12") which is filled with a insulating gaseous medium. In such a cable the conduit comprises on one hand a cylindrical metal sheath (10) of plain or low-alloy merchant steel having a carbon content of less than 0.6% and on the other hand a metal shield (12; 12") of non-magnetic material fixed inside the sheath and having a low specific electrical resistivity. Said metal shield (12") may be spaced from the metal sheath (10) along part of the inside of said sheath. Then said shield is perforated (at 22) by holes, slots or the like leading to the space forming a so-called particle trap (20).
(FR)Un cable electrique rempli de gaz ayant une faible emission calorifique et une faible perte d"energie est utilise pour la transmission d"un courant electrique a haute tension. Le cable comprend un ou plusieurs conducteurs (14) espaces les uns des autres axialement dans le cable au moyen d"isolateurs (16) de support a l"interieur d"une conduite (10, 12 ou 12") qui est remplie d"un melange gazeux isolant. Dans ce cable, la conduite se compose d"une part, d"une gaine metallique cylindrique (10) en acier ordinaire ou a faible teneur de carbone inferieure a 0,6% et, d"autre part, d"une protection metallique (12, 12") faite d"un materiau nonmagnetique, fixee a l"interieur de la gaine et ayant une faible resistivite specifique electrique. Cette protection metallique (12") peut etre espacee de la gaine metallique (10) sur toute la longueur a l"interieur de ladite gaine. Ladite protection est perforee (en 22) de trous, fentes ou autres qui communiquent avec l"espace formant un piege a particules (20).
