Power Transmission and Distribution

With FR3 fluid, you can operate your transformers 20°C “hotter” than you can with mineral oil, increasing load capacity up to 20%. This allows your grid to easily and reliably respond to fluctuating load demands—without accelerating asset aging.

In fact, with FR3 fluid in your transformers, you can choose between extending asset life, increasing load capacity, or striking a balance between the two.

FR3 fluid improves transformer performance by managing moisture significantly better than mineral oil can. FR3 fluid draws moisture out of a transformer’s insulation paper and “consumes” free water in the fluid—without producing corrosive sludge.

This can extend the life of the insulation paper, reduce maintenance, avoid dielectric failure due to moisture, and safeguard dielectric strength in colder environments.

Fires involving mineral-oil-filled transformer are more frequent than most people think, and they can cause catastrophic damage to equipment and people. FR3 fluid has more than twice the flash and fire points of mineral oil. In 25+ years, there have been zero reported pool fires in transformers filled with FR3 fluid. FR3-fluid-filled transformers can also be installed with highly simplified containment and can eliminate the need for costly fire-mitigation systems, which may mean reduced insurance premiums.

Made from vegetable oil, with performance-enhancing additives, FR3 fluid is the industry’s first and leading natural ester dielectric fluid. Unlike mineral oil, it is nonhazardous and nontoxic in water and soil.¹ It is also 100% biodegradable in as little as 10 days.

Transformers filled with FR3 fluid require simplified spill containment and remediation. In fact, bioremediation in case of a spill typically does not require costly equipment and labor.
