From its very first validation tests over 25 years ago to the latest installations of FR3-fluid-filled power and distribution transformers across the globe, FR3 natural ester dielectric fluid has led the industry. FR3 fluid enables more cost-effective, more resilient, higher-performing, safer, and environmentally better ways to power how communities live, play, work, and thrive.
Although mineral oil has long been the fallback transformer oil, it simply isn’t the optimal dielectric fluid. In millions of installations worldwide, FR3 natural ester dielectric fluid has proven to be superior in the ways you value the most. We have the leadership, experience, and proof, so you can be sure to take advantage of FR3 fluid’s benefits.
