What are the specifications for servo transformer oil?

The specifications for servo transformer oil typically include a minimum breakdown voltage of 30 kV, a flash point above 140�C, and a viscosity grade of 10 to 15 cSt at 40�C. Additionally, servo transformer oil should have low water content, typically less than 50 ppm, and a high oxidation stability to ensure long-term performance in power transformers. These specifications ensure effective insulation and cooling properties.
