Construction of Prefabricated Electrical Rooms

Prefabricated electrical rooms, often called power distribution centers (PDC) or powerhouses, have become a popular approach in the electrical industry today. The off-site construction of these rooms reduces in-plant construction and downtime.  

The ability to conduct a more comprehensive factory acceptance test (FAT) with all interrelated systems, such as switchgear and SCADA, facilitates cutover and commissioning.

Power Distribution Center Equipment

A PDC can house various types of electrical equipment, including:

  • Medium Voltage Switchgear,
  • Medium Voltage MCC,
  • Low Voltage Switchgear/MCC,
  • Adjustable Speed Drives (ASD or VFDs),
  • HVAC, purge & pressurization systems, distribution transformers and panelboards,
  • High or Low resistance grounding system (HRG & NGR respectively)

Substation Design Experience You Can Trust

The Mangan PDG team has successfully completed custom-designed projects within budget and on schedule for a multitude of clients. Our team of qualified engineers and specialists has been involved in project opportunity identification, development, evaluation, Front End Loading (FEL) process, selection of conceptual design options, basic and detailed engineering, execution, pre-operation activities related to system functional testing, and energization.

We know how complex PDC projects are, and that there are many moving parts. The team of Mangan PDG working on your project will understand that careful planning, transportation logistics, development of lifting, and continuous coordination with the fabricator, as well as coordination with mechanical and structural engineers, are some of the ingredients of successful PDC projects. We have displayed this comprehensive approach in all of the projects that we have conducted so far, and we would be more than happy to tell you more about them.
