sf6 Official website
sf6 Official websiteSF6 is chemically inert and a very efficient infrared (IR) absorber, which make it a very potent greenhouse gas (GHG) whose impact on global warming is estimated to be 24,000 times greater than CO2. Prior studies have not found a "universal" non GHG replacement gas, consequently eliminating or reducing the use of SF6 needs to be investigated on a case by case basis for each application.

SF6 Gas Servicing Equipment. Sulfur Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgear employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distribution
railway insulating gas Decompose Purpose
An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials, semiconductors and conductors conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher
