Superior high-performance formulations for power and distribution transformers.
You may not spend much time considering transformer fluid when ordering new transformers—and it’s something you’ll never want to worry about.
The best way to achieve peace of mind and to deliver superior support to your communities is to use FR3® natural ester dielectric fluid instead of mineral transformer oil. With FR3 fluid, you get improved and reliable performance, increased efficiencies, better safety, minimized environmental impact, and reduced costs.
FR3 fluid provides you with measurable value, helping you improve your business while securing the very best service for your customers and communities.
FR3 fluid: The transformer fluid that outperforms mineral oil
There are many reasons why mineral oil is not the best choice for transformer fluid: explosion and fire risk, compromised transformer/insulation life, limited loading capacity, and environmental damage, among others. Historically, mineral oil may be the longest-used transformer oil. Practically, it isn’t anywhere near the best.
Derived from 100% renewable vegetable oils, FR3 fluid is validated, field- and lab-tested, and in millions of distribution and power transformers (through 420 kVA) worldwide. It’s proven to be the superior dielectric fluid to mineral oil, and is simply THE choice for dielectric fluid in use today. It’s the smart solution—for performance, value, and peace of mind.
