About the Project
At an airport, the electrical system carries loads linked directly to flight safety alongside those serving passenger comfort. The control tower, navigation and communication systems, airfield lighting supplies and security screening equipment cannot tolerate interruption. The Issyk-Kul region is a high-altitude mountain basin with cold winters and large day-night temperature swings, and tourism makes passenger traffic rise sharply in summer. This seasonal profile means transformer and generator capacity must be used efficiently in both peak and off-peak periods.
For an airport of this scale, the typical arrangement is about 2 × 1,600 kVA of transformer capacity from the 10 kV network with a two-section coupled main board. DevPanel boards with 2 × 2,500 A busbars, 65 kA / 1 s withstand and Form 3b – Form 4a segregation feed the terminal, technical block and airside loads from separate outgoing units. A generator of approximately 1,000 kVA takes over flight-safety and terminal security loads by automatic transfer. Baggage conveyors and HVAC are controlled from DevControl MCCs, while DevBox, DevPower and DevComp complete sub-distribution, lighting and reactive power management.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers the complete LV distribution of the airport’s terminal and technical buildings.
- Main distribution boards (DevPanel): 2 × 2,500 A busbars, 65 kA / 1 s, Form 3b – Form 4a, bus coupler and generator transfer.
- Motor control centres (DevControl): MCCs for baggage handling conveyors, AHUs, heating and pump motors.
- Sub-distribution boards (DevBox): IP31 – IP41 boards for check-in, departure lounges, retail areas and technical rooms.
- Lighting panels (DevPower): Controlled boards for terminal, apron perimeter, car park and road lighting.
- Power factor correction (DevComp): Detuned compensation for conveyor drives and HVAC loads.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Flight-safety loads
Tower, navigation, communication and airfield lighting supplies are fed from a separate priority busbar and backed by UPS.
Seasonal load profile
With busy summers and quiet winters, the two-transformer arrangement allows single-transformer operation through the coupler at low load.
Cold climate
Anti-condensation heaters and thermostats protect boards at low temperatures, and outdoor enclosures are selected with a suitable IP rating.
Baggage system continuity
Conveyor lines are split into sections in the MCC so that a fault on one line does not stop the entire baggage flow.
Frequently Asked Questions
What is the installed power of Issyk-Kul Airport?
For an airport 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.
Which loads are treated as priority at an airport?
Typically tower and navigation systems, airfield lighting supplies, security screening equipment, fire detection and emergency lighting.
How is energy efficiency achieved in the off-season?
The coupled two-transformer arrangement allows operation on a single transformer at low load, and lighting and HVAC are controlled according to the flight schedule.
