What are the specifications of Type II transformer oil?

Type II transformer oil specifications typically include a minimum flash point of 135°C, a dielectric strength of at least 30 kV, and a viscosity of 20-30 cSt at 40°C. Additionally, it should have a low pour point, generally below -30°C, and a water content of less than 50 ppm. These properties ensure optimal performance and safety in electrical insulation applications for power transformers.
