The 20 MVA liquid-filled oil-immersed power transformer is designed for energy storage systems (ESS) and grid-connected power applications requiring stable medium- to high-capacity power conversion.

This transformer is typically used in battery energy storage stations, renewable energy integration projects, and utility-scale power infrastructure, where reliable voltage regulation and thermal performance are critical.

With an oil-immersed insulation system, the transformer provides effective heat dissipation, stable electrical performance, and long-term operational reliability under continuous or fluctuating load conditions common in energy storage applications.

The design complies with applicable IEC standards and supports customization of voltage ratings, cooling methods, and protection configurations based on specific project requirements.

What Are the Key Engineering Considerations for Upgrading Distribution Transformers?

Upgrading your transformers seems simple, but a wrong move can cause costly downtime and inefficiencies. This guide prevents that. Key engineering considerations for a transformer upgrade include precise load analysis, lifecycle cost assessment, selecting the right type (oil vs. dry), ensuring installation compatibility, and planning for future maintenance. A holistic approach ensures reliability and cost-effectiveness […]

When Should Distribution Transformers Be Replaced Instead of Reinforced?

If your distribution transformer is aging, the risk is not just failure. It is unplanned outages, safety exposure, missed capacity growth, and long procurement lead times that turn a small problem into a multi-year headache. Replace (not reinforce) when the unit shows irreversible insulation aging, repeat internal fault behavior, lost thermal margin, or when the […]
