Fuchs transformer oils are generally distinguished by controlled base stock quality, stable dielectric performance, and compliance with utility standards for mineral insulating oils. Depending on the specific product, distinguishing properties can include inhibited formulations for oxidation resistance, good low temperature viscosity, high dielectric strength, low moisture content as delivered, and controlled corrosive sulfur behavior. Actual distinguishing characteristics must be confirmed from the exact product datasheet and batch test certificate, because Fuchs offers multiple grades for different applications and standards.
