Turnkey Power Distribution Solution

Factory-built Outdoor Prefabricated Substations designed for 10kV, 20kV and 35kV medium-voltage systems, with transformer capacity up to 10000 kVA. Our turnkey solutions are widely used in utility networks, EPC projects, industrial plants and renewable energy applications, ensuring fast deployment, high safety and long-term reliability.

What Is an Outdoor Prefabricated Substation?

An outdoor prefabricated substation is a factory-assembled and fully integrated power distribution system that combines:

• Medium-voltage switchgear

• Power or distribution transformer

• Low-voltage switchgear

• Protection, control and auxiliary systems

All components are assembled, wired and tested in the factory before delivery, allowing rapid on-site installation and commissioning with minimal civil work.

Depending on project requirements, prefabricated substations are also commonly referred to as:

Compact Substation, Package Substation, Containerized Substation, E-House, Modular Substation or Skid-Mounted Substation.
