Ester Fluid-filled Transformers

Ester Fluid - FR3

FR3TM fluid is a Fire Resistant Natural Ester dielectric coolant that has been specifically formulated for use in distribution and power transformers. FR3 fluid is a soy-based natural ester, biodegradable, nontoxic, and has exceptionally high fire point of 360°C and flash point of 330°C. It is approved by FM Global® and classified by Underwriters Laboratories® as a “Less-Flammable Dielectric Liquid”.

Incorporating unique characteristics such as high dielectric constant, high fire point, and environmental friendliness, FR3 fluid helps

  • Extend the life of transformers
  • Reduce fire protection and substation costs, and
  • Minimise the carbon footprint. 

Wilson Transformer FR3 fluid-filled distribution and power transformers have been certified by FM Global as compliant with the applicable requirements according to Approval class number 3990 - Approval Standard for Less or Non-flammable Liquid-Insulated Transformers.

Wilson Transformer Company has the capability and experience in designing and manufacturing FR3 fluid-filled transformers. Many distribution and power transformers up to 50MVA, 132kV have been manufactured and installed using ester fluid since 2004 for various customers in the Utility, Mining, Oil & Gas and industrial sectors. We have storage and processing facilities for FR3 fluid and service capability including retro-filling existing transformers.
