About the Project
In a hospital, a power failure is not a matter of comfort but of patient safety. Operating theatres, intensive care units, imaging equipment and medical gas systems require a supply that is either uninterrupted or restored within seconds. The Kyrgyz network can experience voltage fluctuations and outages, and the area around Osh on the edge of the Fergana Valley is seismically active. Hot summers also keep the hospital’s air conditioning and hygienic ventilation systems heavily loaded for much of the year.
For a hospital of this scale, the typical arrangement is about 2 × 1,600 kVA of transformer capacity from the 10 kV network and busbars split into normal, emergency and critical sections. DevPanel main boards with 2 × 2,500 A busbars and 65 kA / 1 s withstand feed these sections, and a generator of approximately 1,000 kVA takes over the emergency and critical busbars through automatic transfer. Critical areas are supported by UPS and isolated IT systems. Chillers, air handling units and pumps are controlled from DevControl MCCs, DevBox boards feed the wards, and DevComp and DevPower handle reactive power and lighting.
Devpan Scope and Switchboard Architecture
Devpan’s scope runs from the hospital’s main LV distribution to the mechanical services MCCs and ward boards.
- Main distribution boards (DevPanel): 2 × 2,500 A busbars, 65 kA / 1 s, Form 3b – Form 4a, normal, emergency and critical sections with generator transfer.
- Mechanical services MCCs (DevControl): Motor control centres for chillers, AHUs, medical gas plant and pumps.
- Floor and ward boards (DevBox): IP31 – IP41 sub-distribution for clinical wards, outpatient and support areas.
- Power factor correction (DevComp): Detuned compensation suited to imaging equipment and drive loads.
- Lighting panels (DevPower): Controlled boards for corridor, waiting area, car park and external lighting.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Busbar segregation
Normal, emergency and critical loads are fed from separate busbar sections, and the generator only takes over the emergency and critical sections.
Transfer time
Automatic transfer brings life-safety loads onto the generator within seconds, while operating theatre and ICU loads are bridged by UPS.
Medical IT systems
Isolated IT systems with isolation transformers in theatres and ICU prevent a single insulation fault from interrupting supply.
Seismic and grid risks
Boards are anchored for seismic loads, and voltage monitoring relays initiate transfer during network disturbances.
Frequently Asked Questions
What is the installed power of the Osh Private Hospital Project?
For a hospital of this scale, the installed power is approximately 3,200 kVA with a typical transformer configuration of 2 × 1,600 kVA. The main busbar is typically rated 2 × 2,500 A with 65 kA / 1 s withstand; the MV level is 10 kV and standby comes from a generator of around 1 × 1,000 kVA.
Why do hospitals separate normal, emergency and critical busbars?
The separation reserves generator capacity for the loads patient safety depends on. During an outage, critical loads are restored first and other emergency loads are added in stages.
Which systems do the MCCs control in a hospital?
Typically chillers and cooling towers, air handling units, hygienic ventilation fans, medical air compressors and vacuum pumps, and plumbing pumps.
