A transformer oil data sheet usually lists the oil type and intended application, for example mineral insulating oil for transformers and switchgear. It includes key properties such as density, kinematic viscosity, flash point, pour point, acidity, dielectric breakdown strength, dielectric dissipation factor, resistivity, and sometimes corrosive sulfur status. It also references the governing standards the product is designed to meet, such as IEC 60296 for mineral insulating oils. The sheet typically states handling, storage recommendations, and compatibility notes, plus typical test methods used for each property.
