Deep Natural Ester Insulating Oil

Transformer Oil Grown from Nature, Inherently Superior

Why Choose Deep Natural Ester Insulating Oil?

**Because your transformer deserves another 5-8 years of life.**

Deep Natural Ester Insulating Oil can double, or even multiply, the lifespan of your transformer's insulation system, reducing the need for frequent equipment replacement. One transformer can last as long as multiple units used to, significantly easing inventory pressure.

**Because you might not even need fire protection on-site.**

Its fire and flash points are more than double those of mineral oil (Flash point > 260°C, Fire point > 360°C), complying with international standards including ASTM D6871-17, IEEE Std C57.147-2018, IEC 62770-2024, and IEC 62975. As a K-class certified less-flammable fluid per IEC standards, it allows for the reduction or even elimination of costly fire protection systems, saving significant upfront investment.

**Because you can stop worrying about the environment.**

Derived purely from plants, it poses no contamination risk if leaked, eliminating the need for complex remediation systems. Its carbon footprint is lower than that of mineral oil, providing a solid, verifiable contribution to your carbon neutrality goals.

**Because your transformer's overload capacity gets a real boost.**

Transformer overload capacity is increased by 20%. Facing peak demand or sudden load spikes, your equipment can withstand the stress and perform reliably, enabling a more resilient power grid operation.

Mineral oil is adequate.

But Deep Natural Ester Insulating Oil is simply better.
Longer life, higher safety, greater environmental friendliness.
And you save money in the process.
