Product type
Transformer oil is a type of insulating oil used in electrical transformers and other electrical equipment. It is typically derived from refined petroleum and is designed to provide electrical insulation and cooling for transformers. The oil helps to dissipate heat generated by the electrical components and protects against moisture and contaminants, ensuring the longevity and efficiency of the equipment.
| Chemical composition | Mineral oil or synthetic oil |
| Viscosity | Typically ranges from 10 to 50 cSt at 40°C |
| Dielectric strength | Minimum of 30 kV for insulation |
| Flash point | Typically above 140°C |
| Pour point | Generally below -30°C |
When selecting transformer oil, consider the specific application and operating conditions, such as temperature range and required dielectric strength. It is important to specify the oil's chemical composition, viscosity, and any necessary certifications for environmental or safety standards. Additionally, determine the quantity needed based on the size of the equipment and frequency of replacement to ensure optimal performance.
