ABSTRACT:
A metal-clad electric installation for high tension use includes a metallic housing containing a conductor supported by an insulator and surrounded by an insulating gas. The metallic housing has adjacent sections which are joined by pairs of connected flanges. The insulator has an external border which is interposed between the flanges of two successive sections of the housing and is secured thereto by bolts passing through aligned openings in the flanges and external border, thereby partitioning the housing into tight compartments. In order to dismantle a section without affecting the sealed condition of the adjacent section, the bolts are replaced by screws which are screwed into small nut plates inserted into slots provided in the interface of the external border and the flanges.
