With the rapid development of power industry and continuous expansion of city scales in China, more and more high-voltage equipments installed, while most of these equipments are using SF6 gas as an insulating gas, which is one of the greenhouse gases that results in global warming. Our mission is to handle SF6 gas safely and effectively, so as to protect our planet from warming too fast. Till now we have sold thousands of SF6 recovery and treatment equipments around the world, and over 10 SF6 treatment centers across the country built to purify and recycle SF6 gas. Around 2000 tons recycled SF6 gas provided for power industry in accordance with IEC and national standards. The use of SF6 gas in China’s power industry is closed-loop, and all the gas in SF6 insulation equipment will be recorded. The record including quantity record of new 99.999% purity SF6 gas and unqualified waste SF6 gas. All SF6 gas whether new or old must be monitored and recorded. More new gas purchased, more old gas discharged, SF6 gas quantity will be recorded in the carbon emission index. To reduce SF6 emissions, il est nécessaire de rendre le gaz SF6 recyclable et réutilisable. Les centrales électriques chinoises achèteront un ensemble d'équipements de traitement du SF6 lors de la construction, mais en raison des grandes quantités et de la large répartition des postes électriques, actuellement, il existe deux modes de réutilisation du gaz SF6. L'un est la récupération centralisée, où le gaz SF6 est collecté dans une base de récupération à proximité pour un traitement unifié. Un autre mode est le contrat de service de recyclage, notre personnel apportera l'équipement à la station pour un service de recyclage en signant un contrat de service.
