24/08/2015ABB's new eco-efficient switchgear uses an SF6 alternative gas mixture as the insulation medium and additionally as switching medium for the high voltage switchgear. The fluoroketone based SF6 alternative gas mixture is a chemical compound developed for switchgear applications in collaboration with 3M.
FV1C is a mobile equipment for filtration and recovery of SF6 gas from gas filled electrical equipment. The gas is filtered and pumped, from a gas-filled object, into a standard gas bottle which is connected to the equipment. Evacuation of gas down to 1 mbar. The equipment is built on a chassis with wheels.

May 20, 2020SF6 gas plays a key role in switchgears and the percentage of gas purity has a direct effect on the switching. Commercially, SF6 is supplied in pressurized bottles or liquid tanks. The gas of these bottles has a minimum degree of purity of 99.9% and may possess the following impurities according to IEC 60376: carbon tetrafluoride (CF4) <0.03%
The SF6 LASERCHECK P3:atm uses a novel principle of leak testing (patent pending). The windowed detection chamber inside the system is illuminated by a specifically developed CO2 laser. A sample of the gas mixture from the test chamber is transferred to the detection chamber via a measuring probe. If the sample contains SF6 released from the
15/04/2015TechTopics No. 111. SF6 gas and U.S. greenhouse gas emissions. The use of sulfur-hexafluoride (SF 6) gas globally has been the subject of a large amount of discussion for many years, both in the U.S., and worldwide. SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with
Recent European and North American legislation has focused on greenhouse gases such as SF6, with the target of reducing emissions to 0.5% per annum. As a result, gas density monitoring is essential to improve leakage visibility, notwithstanding the superior performance of modern gas isolated switchgear (GIS).
