Designed to deliver value
Insulating oil is only a small part of what goes into a power or distribution transformer—in terms of materials and cost. But its performance impact is far from insignificant. What you put into your transformer as part of its insulating system can affect not only the kind of service you provide to your communities, but also the value it returns to your business.
Switching from mineral oil to FR3® fluid can bring greater value to your business. Get FR3 fluid details.
Better and more reliable performance. Cost efficiencies. The real deal.
Mineral oil has been the standard go-to dielectric insulating oil for more than 120 years—probably because the alternatives were not good enough. But mineral oil wasn’t designed to do all that today’s transformers have to do, and so it wasn’t designed to provide what today’s businesses, utilities, and communities need:
Exceptional fire safety.
Optimized and flexible load capacity.
Reliable performance in all climates.
Sustainability and biodegradability.
Longer insulation and asset life.
More efficient and smaller design.
Minimized maintenance and spill remediation costs.
Fewer transformer replacements.
Streamlined asset inventory.
Sustainable supply chain.
More than 20 years ago, we developed FR3 natural ester dielectric insulating oil specifically to deliver a safer, robust, reliable, efficient, better-for-the-earth, and cost-effective alternative to mineral oil. If you haven’t yet taken advantage of all the benefits, now’s your time.
The many ways FR3 fluid pays
Increased grid reliability, more effective transformer and fleet design, significantly improved fire safety, and minimized environmental impact come together to create tangible business value.
