Abstract
UN PÓRTICO ARMADO, caracterizado esencialmente por estar constituido por dos columnas y una cercha de dos vertientes, que se componen respectivamente de dos perfiles de hierro laminado en forma de ángulo diedro, opuestos por el vértice, pero no en contacto, sino adecuadamente separados, y uniéndose dichos perfiles por medio de una varilla de hierro redondo en zigzag, que recorre el espacio intermedio, soldándose eléctricamente a los mismos en cada conjunción.
Druckluftschalter mit von Isolatorsäulen getragenen, ständig mit Druckluft gefüllten, spannungsführenden Behältern, in denen die Leistungstrennstellen angeordnet sind
