Abstract

La présente invention concerne un corps isolant destiné à une installation de distribution moyenne tension comprenant une borne côté barre collectrice, et un départ de câble, un disjoncteur de puissance étant noyé dans le corps isolant, et le corps isolant portant une première zone de contact reliée au disjoncteur de puissance, qui sert d'emplacement d'appui pour un contact de commutation mobile d'un sectionneur, et une autre zone de contact destinée au contact de commutation mobile. L'invention a pour objet la conception d'un tel corps isolant qui permet un montage avantageux d'un point de vue technique de fabrication, des installations de distribution moyenne tension, de manière générale pour des réseaux de distribution d'énergie primaires et secondaires, tout en limitant les coûts. A cet effet, l'autre zone de contact se présente également sous la forme d'une zone d'appui destinée au contact de commutation mobile, le contact de commutation mobile se trouve éventuellement sur l'autre zone de contact au lieu de la première zone de contact, et l'autre zone de contact est reliée éventuellement au départ de câble au lieu de la borne côté barre collectrice.
