Along with the promotion of new technology and the application of new equipment and new materials,sulfur hexafluoride gas equipment has been widely used in the power system with its safety and reliability,convenient maintenance and long service life advantages,and has played an important role in the safety,economy and stable operation of the power system.

　　Usual operation personnel and maintenance personnel have a deeper understanding of sulfur hexafluoride gas characteristics,use,harm and how to take preventive measures in daily contact.It has a new idea on the recovery of sulfur hexafluoride gas,and can correctly grasp and use protective clothing,gas mask and other protective equipment,especially in the process of operation and maintenance can do a better job in the relevant safety protection measures.

　　At present,it is known that sulfur hexafluoride gas is a colorless,tasteless,non-toxic,with good insulation gas.Sulfur hexafluoride gas equipment is widely used in power transmission system due to its high insulation strength,excellent arc extinguishing performance,cooling characteristics,nonflammability and thermal stability.However,sulfur hexafluoride gas cooling is a greenhouse gas that has the potential to contribute to global warming.

　　In the domestic sulfur hexafluoride manufacturers market is hot,the competition is increasingly fierce,but most manufacturers are difficult to stand the test of the market.Due to the relative lag of the manufacturers,they did not fully seek to improve their disadvantages,which increased the operating costs of sulfur hexafluoride manufacturers,compressed the profit space,and greatly improved the development speed of the manufacturers.
