Recently, our single-phase pole-mounted transformers were selected by a leading water utility provider in the Philippines to upgrade their aging power infrastructure. This project highlights how Tengyi’s expertise in transformer manufacturing supports essential public services, ensuring reliable water supply for millions.

Project Background

The client is a major provider of water and wastewater services to over ​​6 million residents​​ in the ​​East Zone of Metro Manila​​, a densely populated urban hub. Their operations are critical to public health, sanitation, and economic stability. However, outdated electrical equipment in remote substations led to frequent power disruptions, risking service continuity for communities and businesses.

​​The Challenge​

• Aging Infrastructure​​: Existing transformers were over 15 years old, causing energy inefficiency and voltage instability.
• ​​High Maintenance Costs​​: Frequent breakdowns increased operational expenses and downtime.
• ​​Harsh Environmental Conditions​​: Coastal humidity, typhoon seasons, and salt air accelerated equipment corrosion.
• ​​Scalability​​: The client needed a modular solution to expand services without overhauling entire grids.

​​Tengyi’s Solution: Single-Phase Pole-Mounted Transformers​

After a thorough site assessment, our team recommended installing ​​Tengyi’s 25 kVA single-phase pole-mounted transformers​​ with the following features:

• Customization​​: Adjusted voltage ratios to match local grid specifications (7.97 kV/230 V).
• ​​Robust Design​​: IP55 protection against moisture, dust, and salt spray, ideal for coastal climates.
• Safety Compliance​​: Ensured adherence to Philippine Distribution Code (PDC) and IEC standards.
• ​​High Efficiency​​: Reduced energy loss by 30% compared to older models, lowering operational costs.
• ​​Compact & Lightweight​​: Simplified installation on existing utility poles, minimizing civil works.
• ​​Low Noise Operation​​: Compliant with urban noise regulations, ensuring minimal community disruption.
• ​​Smart Monitoring Compatibility​​: Prepared for future IoT integration to enable predictive maintenance.

As a trusted ​​transformer manufacturer and exporter​​, Tengyi combines ​​years of engineering expertise​​ with a deep understanding of global infrastructure needs. Our products are certified by ​​ISO, CE, and KEMA​​, and tailored to thrive in tropical, arid, and industrial environments.
