ImpactIntroductionScopeAssessmentUsageApplicationsExamplesVariationsEPA and other organizations will update the GWP values they use occasionally. This change can be due to updated scientific estimates of the energy absorption or lifetime of the gases or to changing atmospheric concentrations of GHGs that result in a change in the energy absorption of 1 additional ton of a gas relative to another.See more on epa.govgreenhouse gas - Methane | Britannica britannica/science/greenhouse-gas/Methanegreenhouse gas - greenhouse gas - Methane: Methane (CH4) is the second most important greenhouse gas. CH4 is more potent than CO2 because the radiative forcing produced per molecule is greater. In addition, the infrared window is less saturated in the range of wavelengths of radiation absorbed by CH4, so more molecules may fill in the region. However, CH4 exists in

General Properties of Sulfur HexafluorideUses of Sulfur HexafluorideMajor Application AreasIt is a colourless, odourless, tasteless, non-combustible gas. It is liquefied under its vapour pressure when sent to another location. Contact with the gas may lead to frostbite. While exposed to fire or heat for an extended period, there's a possibility of rupturing the container with great sound. The estimated lifetime of sf6 gasis in the range of 800-3200 years. 1.

low cost gas insulated switchgear sf6 Libya,ComponentsAdvantagesDisadvantagesGas Insulated Switchgear ApplicationsThe Gas-insulated switchgear design can be done using different components like circuit breakers, bus bars, disconnectors or isolators, transformerslike voltage and current, earth switches, lightning arresters, and surge arrestors. When the substation is connected with gas-insulated switchgear then it is called GIMES or gas-insulated metal-enclosed substation. This kind of technology is not invented recently but it is available for the past 30 years.
