Launching a Transformer Using Natural Ester Oil to Reduce Environmental Impact
December 19,2022
Fuji Electric Co., Ltd.
Fuji Electric Co., Ltd. is pleased to announce the launch of the FR3®Fluid-applied transformer, a transformer that uses natural ester oil as electrical insulating oil.
1. Background
Transformers are products that are installed in power stations and substations, and they change the voltage to suit the location and application, such as for factories or buildings. Transformers generally use mineral oil to insulate and cool windings and iron cores; however, this product uses FR3®*Fluid, a natural ester oil derived from soybean oil.
Demand for this product is increasing as environmental awareness grows, and it is expected that transformers that use natural ester oil will account for about 6% of the global transformer market in 2025 and that the market size will double compared to 2021 (source: Global Ester Transformer Oils Market Research Report 2020). Natural ester oil is less flammable than mineral oil and its usage is expected to expand in places that prioritize fire prevention.
Fuji Electric will contribute to reducing environmental impact by proposing this product to industrial plants in Japan and overseas as well as to data centers and water treatment plants, for which markets continue to grow.

2. Product Features
・ Reduces environmental impact
Natural ester oil is highly biodegradable and non-toxic, so it reduces environmental impact in the event of an insulating oil spill. It’s also plant-derived, so compared with mineral oil, it can reduce CO2 emissions throughout the product life cycle, from production to disposal.
・Reduces deployment costs
Natural ester oil has a higher flash point and Fire point than mineral oil, so it is less flammable and it could allow for the simplification of ancillary facilities like fire walls, oil retaining walls, and oil removal facilities. This could potentially help to reduce the cost of insurance premium, contributing to reducing deployment costs.
