sf6 gas Handling Analysis - Protech PAS

sf 6 provides extremely good electrical insulation and very effectively quenches electric arcs. These properties of insulating gas make it possible to build electrical equipment and apparatus that are compact, use a small amount of material, are safe and will last a long time. Complete gas insulated substations, GIS or RMU, are used where space is restricted, or the environment is severe.
