High-temperature silicone oil provides several advantages:

Thermal Stability: Maintains its properties at elevated temperatures, preventing degradation.
Extended Operating Range: Allows transformers to function effectively in high-temperature environments.
Reduced Aging: Slows down the thermal aging process of transformer insulation materials.
Fire Safety: Lower flammability reduces the risk of fires.
Reliability: Enhances overall transformer reliability and lifespan under demanding conditions.
These benefits make high-temperature silicone oil suitable for transformers operating in harsh environments or under heavy electrical loads.
