About the Project
The main production building of a factory connects loads of very different character to a single distribution system: production line machinery, compressed air plant, overhead cranes, process heating and cooling, and the lighting and ventilation of large halls. Production lines are often rearranged or extended over time, so the distribution system must be flexible and open to expansion. Cold climate conditions add significant loads for hall heating and air curtains.
For a plant of this scale, the typical architecture is a two-section main board fed by two transformers, with MCCs and sub-boards distributed across the halls. Spare outgoers and busbar capacity are reserved on the main board for future lines. Energy analysers meter each line and utility separately, so consumption can be tracked against output. Form 4b and IP54 construction support both maintenance continuity and reliable operation in a dusty production environment.
Devpan Scope and Switchboard Architecture
Devpan supplied low-voltage distribution for the main production building, from the transformer outgoers to machine and lighting circuits.
- Motor control centres (DevControl): motor feeders for production lines, compressors and ventilation fans.
- Main distribution boards (DevPanel): 2 × 4,000 A busbars, 80 kA / 1 s, Form 4b, IP54, spare outgoers and generator transfer.
- Power factor correction (DevComp): automatic reactive power compensation for inductive motor loads.
- Sub-distribution boards (DevBox): line-side boards, workshops and maintenance areas.
- Lighting and power panels (DevPower): production hall, warehouse and welfare area lighting.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Designed for expansion
Spare outgoers and busbar reserve on the main board make it easier to add new lines without shutting the plant down.
Energy metering
Line-level energy analysers allow consumption to be compared with output and efficiency to be tracked.
Crane and compressor loads
Intermittent loads such as cranes and compressors are fed from separate outgoers to limit voltage fluctuation.
Selective protection
Coordination between line boards and the main board prevents a single machine fault from stopping a whole hall.
Frequently Asked Questions
What is the installed power of the Main Production Facility Project?
For a production 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 leave spare capacity in factory switchboards?
Production lines change and grow. Spare outgoers and busbar capacity let new loads be connected without replacing switchboards.
What does power factor correction bring to a factory?
Motor-dominated loads lower the power factor. Automatic compensation reduces reactive energy charges and frees transformer capacity for active power.
