  • Optical technology for detecting the decomposition products

    Sulfur hexafluoride (SF 6) is a reliable insulating gas and has excellent arc-extinguishing properties. SF 6 -insulated electrical equipment, such as switchgear, transformers, and lines, is widely used in city power grids and ultrahigh-voltage power transmission systems owing to its small footprint, high reliability, and long service life.

    The national government should take measures to reduce six GHGs, i.e. carbon dioxide, methane, nitrous oxide, HFCs, PFCs, and sulfur hexafluoride. It should also take measures to enhance the removal of CO2 by sinks such as forests and urban green areas. Moreover, it is to promote research and development, international cooperation, and environmental education for the mitigation of global warming.
