What are Cooper transformer oil specifications?

Cooper transformer oil specifications typically include a minimum flash point of 140°C, a dielectric strength of at least 30 kV, and a viscosity range of 10 to 15 cSt at 40°C. Additionally, the oil should have low water content, generally below 0.1%, and a neutralization number not exceeding 0.03 mg KOH/g. These specifications ensure optimal performance and safety in power transformer applications, maintaining insulation integrity and thermal stability.
