  • The Problem with Humidity in insulating gas 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).
