The SF₆ ring main unit (RMU) is a type of high-voltage switchgear that utilizes sulfur hexafluoride (SF₆) gas as the primary medium for insulation and arc extinguishing; it is widely used in 50Hz AC power distribution systems rated at 12kV (or 24kV). Its core design involves sealing critical components—such as the switch—within a stainless steel gas chamber filled with SF₆ gas, thereby achieving full insulation and complete sealing, which significantly enhances the equipment’s compactness, reliability, and environmental adaptability.
