When should ester transformer oil be used?

Ester transformer oil should be used when enhanced fire safety and environmental protection are priorities. It is particularly suitable for applications in areas with strict fire regulations or where transformers are located near flammable materials. Additionally, ester oils offer better biodegradability and lower toxicity compared to mineral oils, making them ideal for environmentally sensitive locations. They also provide excellent thermal and electrical properties, improving the overall performance and lifespan of the transformer.
