About the Project
In industrial facilities, most of the electrical load comes from motor-driven equipment such as pumps, fans, compressors and conveyors. Direct-on-line starting of large motors can cause voltage dips that disturb sensitive equipment on the same busbar. Russia’s long, cold winters add the risk of condensation and low temperatures in unheated plant rooms. Process interruptions translate directly into lost output and restart costs.
For a facility of this scale, the typical solution is a two-section main board with a bus coupler, fed by two transformers, plus motor control centres placed close to the process. Large motors are fed through soft starters or variable speed drives to limit starting currents. Form 4b separation and withdrawable outgoers allow a faulty motor feeder to be replaced while the plant keeps running. Two generators provide standby power for a safe process shutdown and critical utilities.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers low-voltage distribution and motor control from the transformer outgoers to process motors and utilities.
- Motor control centres (DevControl): direct-on-line, soft-start and VSD feeders for pumps, fans, compressors and conveyors.
- Main distribution boards (DevPanel): 2 × 4,000 A busbars, 80 kA / 1 s, Form 4b, IP54, coupler and generator transfer.
- Power factor correction (DevComp): stepped, detuned compensation for motor reactive power.
- Sub-distribution boards (DevBox): workshops, stores, laboratory and administrative areas.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Motor starting currents
Soft starters and drives on large motors reduce voltage dips and mechanical stress.
Withdrawable MCC feeders
A faulty feeder can be swapped quickly while other motors keep running, shortening downtime.
Board rooms in cold climates
Anti-condensation heaters and thermostats prevent moisture and low-temperature problems in switchrooms.
Safe process shutdown
During a utility outage the generators supply the loads needed to bring the process to a controlled stop.
Frequently Asked Questions
What is the installed power of the Kotok Facility Project?
For an industrial facility of this scale, the installed power is approximately 5,000 kVA, with a typical transformer configuration of 2 × 2,500 kVA. Main busbars are typically rated 2 × 4,000 A with 80 kA / 1 s withstand, supplied at 10 kV and backed by 2 × 1,250 kVA generators.
Why are MCCs preferred in industrial plants?
An MCC gathers motor feeders into standard modules in one place, simplifying monitoring, protection, maintenance and spare parts management.
What does IP54 protection provide?
An IP54 enclosure is protected against dust and splashing water from any direction, a suitable level for dusty and damp industrial environments.
