1. Classification: Transformer oil
2. Executive Standard: GB 2536-2011 T-20 ℃ (general).
3. Precautions：
Storage safety: When storing and managing transformer oil, attention should be paid to safety matters, observing relevant laws and regulations and safety operation procedures to prevent accidents due to improper operation.
4. Quality of transformer oil：
The quality of transformer oil mainly depends on the structural components and refining degree of the oil base. During the operation of transformer oil, its basic functions should be oxidation stability and fluidity. In the past research and application process in China, the oil used for 500 kV ultra-high voltage transformers was referred to as "ultra-high voltage transformer oil", which was then transformed into "distinguishing transformer oil levels based on voltage levels".
Internationally, the latest standards for transformer oil are classified based on indicators such as oil-based structural components and oxidation resistance. With the official implementation of the new national standard GB2536-2011 for transformer oil, the varieties and grades of domestic transformer oil have been unified with international standards. The following table shows the correspondence between different grades in the new and old standards GB 2536-2011 and GB 2536-1990.
