  • The Problem with Humidity in gaz sf6 Gas-Insulated Systems

    Humidity in SF 6 Gas The SF 6 in the gas compartment can absorb a certain amount of water. When the amount of water exceeds the saturation point of the gas, the excess condensates and forms a water layer (if the gas temperature is above freezing) or sublimates and forms an ice layer (if the gas temperature is below freezing).

  • Why gaz sf6 or Sulfur Hexafluoride gas is better for arc

    insulating gas decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into sf6 gas so well that it is not necessary to replenish the Sulfr hexafluoride in GIS. There are some reactive decomposition byproducts formed because of the interaction of sulfur and fluorine ions with trace amounts of moisture, air, and other contaminants.
