Abstract

L'invention concerne un isolateur haute tension, notamment un isolateur support par exemple employé pour supporter des barres conductrices ou des lignes électriques, par exemple dans des installations de transmission de courant continu haute tension ou des installations haute tension. Selon l'invention, les isolateurs supports creux individuels réalisés en matériau composite sont reliés au moyen d'un élément d'accouplement de telle manière que les volumes intérieurs libres respectifs des au moins deux isolateurs supports séparés forment un seul espace de gaz commun.
