The pantograph disconnector consists of two articulated half-arms which, by moving in a coordinated way and “vertically” on the plane of the insulators, close the circuit on a fixed contact connected the upper busbar.
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.
Compared to the semi-pantograph disconnector (SSP), the pantograph model provides a wider contact zone which makes it suitable for substations with busbars made up with flexible conductors.
