Colorless or light yellow transparent liquid, it owns excellent electrical insulation properties and resistance to ozone, corona. It has low surface tension, cut resistance, large compress. Methyl silicone oil has better high temperature resistance, radiation resistance, lubrification and solubility property foe temperature:-50℃-250℃.

Used in insulation, lubrication, damp, shockproof, moisture proof, dustproof and high temperature hydraulic oil, heat bearer, 250-30 is mainly used as dipping oil of power capacitor. It has wide range of working temperature, good safety and degassing property, dielectric property. Also can be used as transformation.
