Abstract
Il est décrit une bague à faible consommation d'énergie pour un transformateur, la bague comprenant un corps denveloppe allongé pour loger un conducteur sétendant le long dun axe longitudinal et ayant des premières et deuxièmes extrémités terminales, les extrémités sétendant à partir de côtés opposés du corps denveloppe; et une bride de fixation ajustée au corps denveloppe afin de permettre à la bague dêtre montée sur une enveloppe du transformateur. Le corps denveloppe comprend une première couche disolation électrique et une deuxième couche disolation électrique entourant partiellement le conducteur, la première couche étant fournie essentiellement par un premier matériau polymère à lintérieur duquel se trouvent des écrans à faible consommation, et la deuxième couche étant fournie essentiellement par un deuxième matériau polymère, les couches étant disposées autour du conducteur de sorte que la bague soit essentiellement exempte de cavités. Dans une réalisation, la première couche définit un noyau intérieur, la deuxième couche fournissant une enveloppe extérieure qui couvre au moins partiellement le noyau intérieur.
