resources and increase competitiveness. sf6 gas gas has been used in industry since the 1940s due to properties such as high dielectric strength, chemical stability, nontoxicity, good insulating properties, good heat transmission ability, and arc-extinguishing capability. Particularly, it has been frequently used since the 1980s for circuit breakers and ring main units. In addition to this, Sulfr hexafluoride gas is ffely used in 380/154 kV substations, gas-Get price

PRESS RELEASE: Fluke Ti450 sf 6 Gas Leak Detector Reduces

Everett, Wash., May 22, 2017 – Identifying leaks of sulfur hexafluoride (insulating gas), which is used as an electrical insulator in extremely high-voltage utilities applications, generally requires the purchase or rental of an expensive gas detector or hiring an outside consultant. The alternatives are shutting down equipment and using a sniffer, which after some time, can determine only the approximate area of the leak, or coating the entire equipment in soapy water and inspect, which is extremelyGet price
