Organic silicon oil transformer-HongYe silicone

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: Appearance: transparent liquid ( suspended substance ) Viscosity, ( 25 ℃): 50 CST Specific gravity, (25): 0.960 The refractive index ( 25 ℃): 1.402 Volatility (150 ℃, 24 hours of weight loss ): 0.5 Pour point, C: -55 Lightning, C: 300 The ignition temperature,℃: 320 Oxygen index: 21.4 Specific heat ( kcal / g, c ): 0.36 Thermal conductivity ( card / cm, second•C ): 3.7*0.004 Coefficient of thermal expansion ( 25 - 150 ℃) ( cm3 / cm3 / degree ): 10.55*0.004 Breakdown voltage ( 25 ℃, KV ): 35 The volume resistance ( 25 ℃, ohm cm ): 1000000000000000 Power factor ( 60 Hz ): 25 ℃: 0.0001 100 degrees: 0.0005 The dielectric constant ( 25 ℃, 60 Hz): 2.7
