Double-Break Disconnectors TYPE SSBIII
Center-Break Disconnectors TYPE SSBII
The pantograph mechanism is installed on the support insulator and transfers the movement of the rotating insulator to the arms of the pantograph disconnector.
The mechanism is housed in an aluminium enclosure, protecting it against pollution and ice. The springs that compensate the weight of the pantograph arms are also installed in this housing.
Each pantograph is equipped with four aluminium arms to ensure a rigid construction with a very high short circuit rating.
The main contacts are made of copper, with a silver plated surface. The counter contact is a horizontal copper bar, silver-plated,which has to be connected to the busbar system.
