Abstract
1.perfeccionamientos introduced in a switch assembly of electrical circuit of multiple disconnections for high voltage, whose set comprises a single first hollow insulating column, vertical, a mechanism housing mounted on said first column and structurally connected with a pair of second hollow columns that they extend angularly, additional mechanism housings mounted on each of the second hollow columns, at least a pair of arc-extinguishing, double-disconnected, V-shaped interruption units, mounted on one of said second hollow columns, supporting the second hollow column adjacent to at least one additional interruption unit with arc extinction, and mechanical means comprising insulating interconnection operating stems that extend through the column structures to drive the units, the units being operatively interconnected as a set of multiple disconnections in a high voltage transmission line circuit.
