During an electrical discharge, this gas quenches arcs by splitting apart. Its six fluorine atoms capture errant electrons, and then the molecule quickly recombines. It is much more effective than air or nitrogen as an insulator.<\/p>\n<p>That\u2019s under ideal conditions, though. No matter how careful service technicians are, tiny amounts of <strong>reactants<\/strong> found in ambient air \u2013 namely <a href=\"https:\/\/blog.wika.com\/us\/\/products\/sf6-products\/water-impurity-sf6-gas\/\">water<\/a> (H<sub>2<\/sub>O) and silica (SiO<sub>2<\/sub>) \u2013 invariably find their way into a gas compartment. Water compromises the gas\u2019s insulating strength by preventing SF<sub>6<\/sub> from fully recombining after an electrical discharge. When this happens, sulfur and fluorine combine with hydrogen and oxygen to form other compounds (Figure 1).<\/p>\n\n      <div class=\"wp-caption aligncenter\" style=\"max-width:846px;\"><img
