The oil commonly used is mineral insulating oil, often specified under standards such as IEC 60296. Depending on application, natural ester, synthetic ester, or silicone insulating fluids may also be used. The selected oil must meet dielectric, thermal, chemical, and environmental requirements defined by transformer design and operating conditions.
