What the shared parts are
- HV switchgear, GIS, breakers, protection relays — The high-voltage switching, protection, and fault-isolation gear between the substation transformers and the campus's medium-voltage distribution, including gas-insulated (GIS) designs for compact sites.
- MV switchgear, E-houses, power skids — Medium-voltage switchgear packaged into pre-fabricated electrical houses (E-houses) or skids that distribute power across a campus and can be factory-built and shipped as modules.
- LV switchgear, switchboards, panelboards — Low-voltage electrical distribution equipment — switchgear, switchboards, and panelboards — that receives power from MV/LV transformers and distributes it onward to busway, PDUs, and building loads.
- UPS (static, modular, rotary/DRUPS) & UPS power semis — Uninterruptible power supplies that bridge the gap between a utility outage and generator start, built as static (battery-based), modular, or rotary/diesel-rotary (DRUPS) designs, plus the power semiconductors inside them.
