Natural ester insulating fluid is biodegradable and carbon neutral.
It can extend the life of insulation materials, increase load capacity and improve fire safety, while reducing environmental impact, thereby helping to improve the reliability and flexibility of the power grid.
Widely used in power equipment such as power and distribution transformers, more than 2 million units have been used worldwide with zero fire records.
With FR3 natural ester technology, users can achieve:
● Reduce transformer size and improve efficiency
● Improve fire safety (FR3 natural ester has a flash point and fire point twice that of mineral oil)
● Extend the life of transformer insulation materials (5 to 8 times that of mineral oil)
● Increase load capacity (high temperature resistance can be improved by up to 20% with FR3 natural ester)
● Reduce environmental impact because FR3 natural ester is biodegradable, non-toxic and carbon neutral
● Vegetable oil mainly derived from soybeans, with a fire point of up to 360 degrees, is flame-retardant, non-toxic, non-corrosive and easily degradable.
Flash point is the most critical factor for transformer fire safety：
● FR3 Flash point = 360℃
● Transformers filled with FR3 have a fire record of 0
● K-class, flame-retardant fluid
● UL and FM certified
● Power transformers
● Eliminate sewage systems and fire walls
● Reduce the distance between equipment and buildings
● Meet fire regulations by changing oil without replacing or removing equipment
Advantages compared to mineral oil: Mineral oil:
1. Fire risk
● Flash point is only less than 40℃ higher than the transformer operating temperature limit
2. Low biodegradation rate
3. Low water saturation
● Especially at low temperatures, dielectric properties may be reduced/free water may be generated
4. Oxidation may form sludge, causing aging of paper insulation and reduced dielectric properties
FR3 natural ester:
1. Continuously dry solid insulation material
● Proven to reduce the aging rate of insulation paper
● Enhance load capacity and reliability
2. Improve fire safety
● Highest ignition point (>360℃) of Class 1 liquid
● Best environmental performance, reducing environmental impact
3. Maintain dielectric properties at extremely low temperatures
4. Reliable solution for all non-free breathing transformers
