2019/9/13Climate change: Electrical industry's 'dirty secret' boosts warming. It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned
22kv sf6 gas Dew Point analyzer
Gas Insulated Switchgear For SF6 filled gas compartments, SF6 in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew point no higher than – 5 C. Gas compartment
35kV insulating gas weight Disadvantage
Thermal insulators work by trapping bubbles or pockets of gas inside a foam structure. When these cells of gas are filled with moisture, there are significant losses in insulating efficiency. The thermal conductivity of water (at 10 &C) is 0.5 kcal m 1 h 1 &C 1 and that of ice (at 0 &C) is 2 kcal m 1 h 1 &C 1 (about four times the value of water).

110kV insulating gas Norms Process
The Blue GIS 8VN1 from Siemens Energy is an innovative, compact switchgear product. 8VN1 doesn't use Sulfur hexafluoride (SF6 gas) or other fluorine gases as an insulating and interrupting medium. Instead of greenhouse gases, it uses compressed synthetic air (so called clean air) technology to provide insulation between live parts and the earthed metal housing.
35kV Sulfur Hexafluoride standard Dangerous
35kV Sulfur Hexafluoride standard DangerousSulfur hexafluoride is an extremely potent greenhouse gas that is used for several purposes when transmitting electricity through the power grid. EPA is working with industry to reduce emissions through the SF 6 Emission Reduction Partnership for Electric Power Systems, which promotes leak detection and repair, use of recycling equipment, and employee training.
