1-Arm Pantograph Type
Vertical Reach disconnectors are the best solution for busbar selection, since they can ensure isolation/connection directly across the vertical gap between lower and upper busbar. More than 30 years of experience in this design ensures the necessary performances and sturdiness to fulfil all possible requirements, worldwide.
This design allows easy bay maintenance since the all the switchgear and components of the line (including the disconnector itself) can be reached while the upper busbar is energized. Furthermore, the bay is more compact than with every horizontal disconnecting solution.
The 1-arm pantograph, has been proven by more than 30 years of use in EDF-RTE ( France ) and ENEL-TERNA ( Italy ). For high-end performance, the SSP gives the most compact and efficient solution, thanks to its dissociated kinematics and electrical functions.
The live parts are made of aluminium, hard drawn silver plated copper, with stainless steel hardware. The high performance rotary contacts are self cleaning and can bear thousands of cycles maintenance-free. The base frame and all steelworks are hot dip galvanised.
This product is available from 170 kV to 800 kV (BIL 2100), and up to 4000 A .
