Gas Insulated System an Introduction of GIS - About Circuit· The SF6 gas is not flammable. But oil is flammable. So, SF6 gas reduces the chance of fire hazard to a very minimum or zero. The dielectric strength of sf6 gas is three times higher than that of air. Again if we increase the pressure of the sf6 gas, it enhances the dielectric strength of the gas further. So, we can construct a significantly ...
