what is flash point of transformer oil?

The flash point of transformer oil is the lowest temperature at which the oil can vaporize to form an ignitable mixture in air. Typically, transformer oils have a flash point ranging from 130�C to 180�C (266�F to 356�F), depending on their specific formulation and additives. This property is crucial for ensuring the safety and stability of transformers, as it helps prevent fire hazards during operation and maintenance.
