What are Caltex transformer oil specifications?

Caltex transformer oil specifications include key parameters such as dielectric strength, viscosity, flash point, and pour point. The oil must have a minimum dielectric strength of 30 kV for effective insulation, a viscosity of 10-15 cSt at 40°C, and a flash point above 140°C. Additionally, the pour point should be low enough to ensure fluidity in cold conditions. Compliance with ASTM D3487 and IEC 60296 standards is essential for optimal performance in power transformers.
