• for customer substations, distribution substations and switching substations of utilities
• in public buildings such as high-rise buildings, airports, hospitals, sports arenas
• in industrial plants.
The ratings of your SIMOSEC panels are provided on the rating plates.
The following systems
are used:
• Individual panels, for free combination and extension
• Three-pole primary enclosure
• Phases arranged one behind the other
• Bus bar system at top or bottom, as needed for the application
• Air-insulated bus bar and cable connection system for conventional cable terminations
• Three-position switch-disconnector, metal-enclosed, with air-insulated primary termi-
nals and gas-insulated switching functions (maintenance-free quenching system)
• Switching devices in stainless-steel SF
6
-filled vessel, without seals, with welded-in
bushings (sealed for life)
