The semi-pantograph disconnector consists of one articulated arm which, by moving “vertically” on the plane of the insulators, closes the circuit on a fixed contact connected to the upper busbar.
Semi-pantograph disconnectors are an ideal solution for connection to busbar systems, since they allow minimizing the substation area and ensure the maintenance (disconnector arms included) of the bay inside which the equipment is installed, without putting the upper busbar out of service.
