For the performance you want and the reliable power your communities need, FR3 fluid beats mineral oil - it’s that simple. Mineral oil has helped light and power the globe for more than 120 years. But for decades, another option has proven better. FR3 dielectric fluid - derived from 100% renewable vegetable oils - delivers what transformer mineral oil can’t: peace-of-mind reliability with exceptional performance, improved fire safety, and better-for-the-planet biodegradability, along with related cost savings.
