Sulfur hexafluoride (SF₆) gas: an industrial tool for efficient insulation and arc extinguishing

In the modern industrial field, sulfur hexafluoride (SF₆) gas has become an indispensable key material in power equipment, electrical switches and high-voltage equipment due to its excellent insulation performance and arc extinguishing ability. As a colorless, odorless and non-toxic gas, SF₆ shows extremely high stability under high-voltage environments and is widely used in power transmission, substations, circuit breakers and gas insulated switchgear (GIS).
