Designed for North & Latin American Distribution Networks
The 225 kVA pad-mounted transformer is specifically engineered to align with utility practices and regulatory requirements across North America and Latin America. In the United States and Canada, it meets ANSI and IEEE standards commonly specified by electric utilities, municipalities, and commercial developers. In Mexico, Brazil, Argentina, Chile, Colombia, Peru, and Costa Rica, the transformer supports regional voltage classes and installation methods used in both public and private distribution networks.
Its pad-mounted design allows for safe ground-level installation, making it ideal for underground cable systems, where aesthetics, public safety, and space efficiency are critical. The sealed tank and outdoor-rated enclosure protect internal components from moisture, dust, and environmental exposure, ensuring reliable operation in diverse climates—from cold northern regions to tropical and coastal environments.
Factory Direct Sales for Cost Efficiency and Project Control
Unlike resellers or trading companies, Yawei Transformer supplies this 225 kVA pad-mounted transformer directly from the factory, giving customers clear advantages in pricing, lead time, and customization control. Factory-direct sales reduce unnecessary markups while enabling close coordination between engineering teams and project stakeholders.
For EPC contractors, utilities, and wholesale buyers, this means:
-
Competitive factory pricing for bulk or long-term projects
-
Direct technical communication during design and approval stages
-
Flexible configuration based on grid requirements and site conditions
-
Consistent quality control from production to shipment
This approach is particularly valuable for large-scale distribution projects in North and Latin America, where cost transparency and technical compliance are essential.
Custom MV–LV Design to Match Utility Standards
Every power distribution project has unique technical requirements. The 225 kVA pad-mounted transformer can be customized with medium-voltage to low-voltage (MV–LV) configurations to match utility standards, load characteristics, and future expansion needs.
Available customization options include:
-
Primary voltage selection from 13.2 kV to 34.5 kV
-
Secondary voltage tailored to commercial or industrial loads
-
Vector group and grounding configuration adjustments
-
Choice of insulating oil (mineral oil or environmentally friendly fluids)
-
Optional accessories such as surge arresters, loadbreak switches, and monitoring devices
This flexibility ensures seamless integration into both new installations and existing underground distribution networks.
ANSI / IEEE Compliance and Utility-Grade Reliability
Reliability and compliance are critical for pad-mounted transformers used in public and commercial environments. This 225 kVA unit is designed and tested in accordance with ANSI and IEEE standards, covering electrical performance, insulation levels, temperature rise, and mechanical strength.
Each transformer undergoes routine factory testing to verify:
-
Voltage ratio and polarity
-
Insulation resistance and dielectric strength
-
Load loss and no-load loss performance
-
Temperature rise under rated load
Optional certification support for CSA, UL, or CE can be provided to meet specific project or regional requirements.
