Organic silicon oil transformer

         Combustible silicone transformer oil is small, only when the oil temperature up to 350℃combustion, combustion heat release in small and self-extinguishing. The dielectric constant of silicone transformer oil are high, chemically inert, and changes in temperature range of 40 to +250 small viscosity, no environmental pollution, and can be applied to a fire, explosion and other dangerous places.

        The main production of silicone transformer oil abroad with the United States of America General Electric Company 's SF-95[50] and Tao Kangning 's DC-561. SF-95[50] silicone transformer oil is a viscosity of 50 CST poly two methyl siloxane. The following are the physical performance index:
