Sulfur hexafluoride | F6S - PubChem

Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (sf6 gas has an estimated lifetime in the atmosphere of between 800 and 3,000 years).Get price

Pushing the limits of technology | TD World

Gcb Technology AdvancesAir-Blast Compared with gaz sf6 TechnologyReliable and Safe Power GenerationProtecting The WorldLargest Power PlantsABB further pioneered the development of circuit breakers that use phase-segregated busducts with higher unit ratings in the 1960s. In the 1980s, ABB successfully introduced gaz sf6 GCBs using a three-phase system in single-phase enclosures. Meanwhile, the life-cycle costs of installed GCBs with air-blast technology became too expensive in terms of service and maintenance costs, therefore ABB continued to develop state-of-the-art sf 6 GCB technology throughout the 1990s and phased out air-blast technology. Since then ABB has introduced various new types of GCBs with increased functionality to the market - most recently type HEC 9 with the worldhighest short circuit current breaking capability at 250 kA using Sulfr hexafluoridetechnology at a rated maximum voltage of 31.5 kV. HEC 9development is an upgrade of the design and development of the GCB type HEC 7/8, which is able to cope with short-circuit currents up to 210 kA and to handle rated currents of 50,000 A or more, where the latter requires...Get price

“We are closed, we have no power.” An electrifying personal

Mar 03, 2021 · At very cold temperatures gasses tend to turn to liquids. And this is very bad. When gaz sf6 in gas breakers start to liquefy the breakers start to misoperate. All these potentially lead to outages. Also, equipment when not properly insulated or weatherized starts to freeze, like the well heads and pipelines for the natural gas supply.Get price
