I'm discussing a proposed project where customer wishes to place new 69kV GIS switchgear in a pre-fabricated building. Most buildings I've seen with GIS switchgear had a cable vault in basement of building for routing of cables below switchgear and then terminating through floor to switchgear.
Has anyone seen what is typical or standard with GIS in pre-fabricated elevated buildings? I've seen conceptually where some have GIS on elevated 2nd floor with first floor (ground level) being dedicated to cable management. If routed below building in this case should ground floor be enclosed or can it remain open with cable tray below the building?
Incoming/outgoing cable will be both UG ductbank as well as OH cable tray.
I'm also curious to hear from others who have done GIS in pre-fabricated buildings if its typically better to install GIS gear at the building manufacturer to ship with building or install once building has arrived on-site?
