Mineral insulating oil is widely used in transformer equipment due to its mature technology and low price. However, mineral insulating oil has certain toxicity to organisms and degrades slowly in natural environments.  Once it leaks, it will cause serious pollution to the environment, and the subsequent environmental remediation cycle is long and costly. With the increasing awareness of environmental protection, more and more users choose green and environmentally friendly natural ester oil. Cargill FR3® natural ester, which combines the advantages of fire prevention, environmental protection and cost reduction, provides a more economical and green solution for the field of offshore wind power generation.

Cargill FR3® is a pioneer and leader in natural esters. It has been validated by the OECD standard for mammalian and aquatic toxicity tests, and is non-toxic to mammals and aquatic organisms. It can be rapidly degraded in natural environments. Compared to mineral oil, FR3® natural ester leakage has a small impact on the environment, low remediation costs, and no pollution to water and soil.FR3® natural ester has been successfully applied in offshore wind power, fishery-photovoltaic and agriculture-photovoltaic complementary photovoltaic projects, and hydropower, pumped storage, and offshore photovoltaic projects are also being actively promoted.
