Medium Voltage SSIS switchgear
Shielded Solid Insulation System (SSIS) is the MV Switchgear technology of the future.
If every part of the power distribution system was adequately shielded, none of the common elements that threaten such a system - air, humidity, erosion, vermin, misplaced tools – would negatively impact its’ performance. Systems whose average maintenance cycles extended to only about three years, could suddenly be serviced in ten.
SSIS/2SIS is the key element of the Premset MV switchgear. SSIS uses dielectric epoxy as a solid insulating material around each bus bar and current-carrying component. Layered on top of that epoxy is a conductive layer that is grounded, the benefit of which is a positive accidental touch-safe rating.
It means that inside the switchgear there is no exposed MV live part. Check out the Premset flooding test at the following link:
