Gas insulated switchgear (GIS) is essential for securing high-voltage substations. It uses gas as the primary insulating medium, such as sulfur hexafluoride (SF6). The gas insulation in GIS prevents electrical arcing and ensures effective insulation. The components of GIS work together to provide reliable performance.
