  • Gas insulated power transformers: A growing technology

    SF 6 gas has lower cooling performance than that of insulating oil. The thermal capacity of the same volume is 177 times lower and the heat transfer coefficient for the same flow velocity is 7,3 times lower (SF 6 gas with gas pressure 0,12 MPa-g, at 20&C). The following measures help to overcome these differences in physical properties:
