Abstract

L'invention porte sur un transformateur/bobine d'arrêt (1) bobiné avec un câble HT (111) et pourvu d'une couche de semi-conducteur (115) et d'entretoises (4, 10, 19, 119) disposés de manière à constituer des tubes de refroidissement cylindriques coaxiaux (3), l'une au moins des entretoises (4, 10, 19, 119) étant électroconductrice, présentant une partie (17, 21) résistant à l'usure, et étant reliée par l'un de ses côtés (13) en suivant un trajet partiellement contournant, à la couche de semi-conducteur (115) du câble HT (111).
