摘要

An integrated system (1) for first- and second-row air-break switches-disconnectors, with simplified maintenance, comprising at least one containment cabinet (2) for a first-row on-load air-break switch-disconnector (8) and at least one containment cabinet (3) for a second-row on-load air-break switch-disconnector (8), which are connected to each other by means of a bar (4), each cabinet (2, 3) being constituted by a housing cabinet (5) and by a carriage (6) which can be extracted from said housing cabinet (5) and is adapted to support an on-load air-break switch-disconnector (8), segregated by busbars by means of at least one automatic shutter (10).
