1. Classification: Transformer oil
2. Executive Standard: GB 2536-2011 T-10 ℃ (general).
3. Application Scope: T-10 transformer oil is suitable for transformers with antioxidant content not exceeding 0.08% as required by users, as well as electrical equipment with similar requirements.
4. Performance requirements for transformer insulation oil：
(1) Flash point and self ignition point: Flash point refers to the lowest temperature at which insulating oil can burn under certain conditions, while self ignition point refers to the lowest temperature at which insulating oil can self burn under certain conditions. The higher the flash point and self ignition point, the higher the safety of the insulating oil.
(2) Antioxidant performance: Antioxidant performance refers to the ability of insulating oil to maintain stability under the action of high temperature and oxygen. The better the antioxidant performance, the longer the lifespan of the insulating oil.
