Energy-saving low-loss distribution transformers are designed to reduce no-load and load losses in medium-voltage distribution systems, helping utilities and industrial users cut lifetime operating costs while improving grid efficiency.

Covering a typical capacity range of 50–2500 kVA, this series is suitable for public distribution networks, industrial power distribution, commercial infrastructure, and renewable-related auxiliary power applications where long operating hours make efficiency gains measurable.

Built with optimized core design and improved winding structure, the transformer delivers stable electrical performance, low temperature rise, and long service life under continuous duty. Configurations can be tailored to local grid requirements, including different primary/secondary voltage levels, vector groups, taps, and protection/accessory options.

Designed for outdoor installation, the transformer can be supplied in conventional oil-immersed construction and specified according to project requirements and applicable IEC / IEEE practices to match common utility specifications and procurement habits.

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 […]
