About the Project
In Tajikistan, winter loads are a major factor in school electrical design: many buildings rely partly on electric heating, and consumption rises markedly in the cold months. In summer, high temperatures create demand for ventilation and cooling. The region is seismically active, and lightning-induced surges arriving over overhead lines can threaten sensitive educational technology. Interactive whiteboards, computer labs and security cameras all need a clean, stable supply.
A school building of this scale typically has about 2 × 800 kVA of transformer capacity supplied from the 10 kV network and a two-section main distribution. DevPanel boards with 2 × 1,250 A busbars, 50 kA / 1 s withstand and Form 3b segregation distribute heating, classroom and common-area loads as separate groups, with surge protection at the incomer. DevBox floor boards include spare ways for future classroom extensions. DevPower handles lighting, DevComp manages the reactive load, and a generator of approximately 630 kVA supplies life-safety loads.
Devpan Scope and Switchboard Architecture
Devpan supplied the school’s entire LV switchboard infrastructure, from the transformer outgoing side to the classroom boards.
- Main distribution boards (DevPanel): 2 × 1,250 A busbars, 50 kA / 1 s, Form 3b, surge protection and generator transfer section.
- Floor and classroom boards (DevBox): Lockable IP31 – IP41 sub-distribution boards with spare ways.
- Lighting panels (DevPower): Programmable control of classroom, corridor and schoolyard lighting.
- Power factor correction (DevComp): Stepped compensation for heating, ventilation and kitchen loads.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Winter heating loads
Electric heating circuits are grouped separately so that load shedding and staged switching can be applied at the winter peak.
Surge protection
Surge protective devices at the main incomer and in computer lab boards protect equipment against lightning-induced transients.
Room for expansion
Spare ways and busbar capacity in floor boards allow future classrooms to be supplied without replacing boards.
Seismic mounting
Enclosures are fixed with anchored plinths and top bracing, with heavy equipment placed low in the enclosure.
Frequently Asked Questions
What is the installed power of the Tursunzade School Project?
For a school building of this scale, the installed power is approximately 1,600 kVA with a typical transformer configuration of 2 × 800 kVA. The main busbar is typically rated 2 × 1,250 A with 50 kA / 1 s withstand; the MV level is 10 kV and standby comes from a generator of around 1 × 630 kVA.
How does electric heating affect switchboard design?
Heating loads draw high current for long periods. They are therefore grouped on dedicated feeders, busbars and cables are sized for continuous duty, and staged switching is used where needed.
Which loads does the generator supply in a school?
Typically emergency lighting, fire detection and alarm, CCTV, the IT room and boiler room controls are placed on generator supply.
