Product Advantages

Excellent heat dissipation: Fast heat conduction and low viscosity enable efficient heat transfer, keeping equipment at a stable working temperature.
Strong insulation performance: High dielectric breakdown voltage prevents short circuits and electric leakage in high-voltage systems.
Good oxidation stability: Resists sludge and acid formation, extending oil service life and reducing replacement frequency.
Wide temperature adaptability: Low pour point and high flash point work well in both cold and high-temperature environments.

Production Advantages

We adopt precision fractionation and strict quality control processes in production, with each batch of oil tested for key performance indicators. Our self-developed additive formula enhances the oil's comprehensive performance, and the automated production line ensures consistent product quality. We also use environmentally friendly production techniques, meeting international environmental and industrial standards.
