What are the specifications of oil-immersed transformers?

Oil-immersed transformers typically feature specifications such as voltage ratings ranging from 10 kV to 800 kV, power ratings from 10 kVA to several hundred MVA, and insulation class ratings of up to 105°C or higher. They utilize mineral oil for cooling and insulation, with a dielectric strength of around 30 kV per mm. Additionally, they are designed to meet standards like IEC 60076, ensuring reliability and efficiency in power distribution applications.
