1. Insulation
High dielectric properties: Ethyl silicone oil possesses excellent electrical insulation properties, effectively preventing internal electrical breakdowns in transformers and ensuring safe operation.

Chemical stability: Its resistance to chemical corrosion maintains its insulation performance over a long period, preventing insulation failure due to dielectric aging.

2. Heat dissipation and temperature regulation
Wide temperature range adaptability: Operating temperature range reaches -60℃ to 150℃. It maintains fluidity even at extreme low temperatures and is not easily decomposed at high temperatures, making it suitable for heat dissipation needs during transformer load fluctuations.

High specific heat capacity: It effectively absorbs and disperses the heat generated during transformer operation, improving heat dissipation efficiency.

3. Vibration damping and mechanical protection
Damping effect: As a vibration damping medium, it absorbs vibration energy during transformer operation, reducing mechanical impact damage to the internal structure.

Lubrication: It reduces frictional losses between metal components, extending equipment lifespan.
