<p>Disclosed is a cell comprising a casing containing a three-phase disconnecting and isolating switch, which ensure interconnection between the bars and/or external electric cables connected inside the casing through sealed press leads. Said casing, being optimally cubic, comprises an isolating switch, the blades (7) of which are in contact in a service position with conducting studs (9); said studs are aligned horizontally and parallel to the front panel of the casing, and are borne by conducting bars (10) orthogonally arranged with respect to this surface, above the isolating switch and the disconnector in the casing. These bars are connected to press leads (17A, 17B, 17C), borne by a top panel (FS) of the casing. In a ground connection position, the blades are in contact with one of the grounding studs (11) borne by a horizontal reinforcing crosspiece (31), centrally arranged between lateral walls in the casing.</p> |
