Product advantages
International certification guarantee
It complies with international standards such as IEC 60296 and ASTM D3487, has passed the ROHS environmental protection certification, and meets the requirements of global market access.
Zinc-free (DDB) and low-sulfur formula, eliminating the risk of equipment corrosion, suitable for harsh working conditions.
Outstanding performance
Ultra-high insulation: Breakdown voltage ≥65kV (measured), effectively preventing arc discharge and ensuring power grid safety.
Long-lasting antioxidant: With the addition of hindered phenolic stabilizers, the oxidation life exceeds 20 years, reducing the frequency of oil changes.
Wide temperature adaptability: Pour point as low as -40ºC, flash point as high as 150ºC, stable performance in extreme climates.
Environmental protection and energy conservation for efficiency improvement
The biodegradability rate has been increased by 30%, meeting the EU REACH regulation and helping customers achieve their ESG goals.
A 15% increase in thermal conductivity accelerates the heat dissipation of transformers, reduces energy consumption by 5% to 8%, and lowers the carbon footprint.
One-stop solution
Supports flexible customization of viscosity (10-100 cSt) and packaging (IBC ton drums/customized specifications) to meet the requirements of different equipment.
We provide oil product testing reports, technical guidance and after-sales tracking services to empower customers to have a worry-free supply chain.
