Abstract

Transformateur à sec sous blindage résistant à la pression et antigrisouteux. Dans l'enveloppe 1 sont montés, parallèlement à l'axe et à distance de la surface latérale interne de cette dernière, des tubes de refroidissement 4 qui, par leurs extrémités, traversent les zones externes 2b, 3b des brides, sont soudés sur celles-ci et sont réunis en un trajet de refroidissement au moyen de bagues de serrage séparées, munies de canaux de renvoi ainsi que d'ouvertures d'entrée et de sortie et fixées sur les zones externes 2b, 3b des brides de l'enveloppe, ce trajet de refroidissement faisant partie d'un circuit de réfrigérant.
