110/6 kV Substation Design and Construction (EPC) for a Cardboard & Paper Factory

About the project

Voltage Group acted as the General Designer and General Contractor for a complete turnkey construction of a 110/6 kV transformer substation at a large cardboard and paper manufacturing facility in central Ukraine. The project was executed to provide a reliable and future-proof power supply system for an energy-intensive industrial production site.

Challenge

The client required a modern and scalable high-voltage substation tailored to the operational demands of the paper and packaging industry. The scope involved delivering a complete engineering and construction solution—from feasibility study to commissioning—while maintaining compliance with all safety, technical, and regulatory standards. One of the key challenges was coordinating the implementation within an active industrial area without disrupting ongoing operations.

Power Substations and Transmission Lines: Design, Construction, and Maintenance

Voltage Group delivered a turnkey 110/6 kV substation for a paper and packaging factory in Ukraine, including full EPC services, switchgear design, relay protection, SCADA, and metering systems—ensuring reliable industrial power infrastructure.

Services provided

Voltage Group delivered full-cycle EPC (Engineering, Procurement, and Construction) services, covering:

1. Technical and Engineering Design:

Development of the full set of project documentation for the 110/6 kV transformer substation.
Design of 110 kV switchgear (VRP-110) using an H5 single-line diagram.
Selection and configuration of 110 kV switchgear components and 110/6 kV power transformers.

2. Medium Voltage Systems and Equipment:

Design and integration of the 6 kV switchgear (RP-6) system for internal plant distribution.
Relay protection systems for both 10 kV and 6 kV networks.

3. Structural and Architectural Engineering:

Architectural and structural design of substation buildings, foundations, and support infrastructure.
Engineering of both concrete and steel structures to support electrical equipment and cable lines.

4. Automation and Metering Systems:

Deployment of telemetry and automation systems for real-time monitoring and control.
Design and integration of electricity metering systems for commercial and operational use.

5. Cable Line Design and Routing:

Engineering solutions for 110 kV and 6 kV cable line installations, including cable trenching and routing.

Outcome

The result was a modern, high-performance 110/6 kV transformer substation that fully meets the energy needs of the production facility—both current and projected. All works were delivered on time, on budget, and to a high technical standard, with full alignment to Ukrainian energy regulations and safety protocols.

The client praised Voltage Group for its:

Strong technical competence and engineering depth.
Proactive handling of operational matters.
Transparent communication and financial integrity throughout the project lifecycle.

This project demonstrates Voltage Group’s ability to provide end-to-end high-voltage substation solutions for industrial manufacturing clients—ensuring safe, efficient, and expandable energy infrastructure.
