Electrical Engineering Services

Electrical load calculations, single-line diagrams, power distribution, cable sizing, cable schedules, lighting and earthing layouts.

Electrical engineering decides how power reaches every motor, heater, light and control panel in a plant, and whether it does so safely. CoreFlow prepares load lists, single-line diagrams, cable sizing and schedules, distribution layouts, and lighting and earthing designs for process plants and industrial facilities.

Our electrical deliverables are coordinated with mechanical equipment lists, instrumentation and HVAC loads and the 3D layout, so cable routes, tray sizes and room layouts fit the plant instead of being fixed on site.

Electrical Engineering FAQs

What is a single-line diagram used for?

A single-line diagram (SLD) shows how power is distributed from the incoming supply through transformers, switchgear and MCCs to each load, with ratings and protection. It is the basis for equipment specifications and cable sizing.

How are power cables sized?

Cables are sized for current-carrying capacity with derating for the installation method, voltage-drop limits during running and starting, and short-circuit withstand.

Do you carry out short-circuit and protection coordination studies?

Yes, where they are included in the agreed scope.

Can you design lighting for process and outdoor areas?

Yes. We prepare illumination calculations, fixture selection and schedules, and indoor, outdoor, road and emergency lighting layouts.
