SafeRing-40.5 Gas Insulated Ring Main Unit (RMU) -SF6 Sealed Switchgear

SafeRing-40.5 Gas Insulated Ring Main Unit (RMU) -SF6 Sealed Switchgear
Details:
Gas Insulated Ring Main Unit (RMU) is compact high-performance SF6 sealed medium-voltage switchgear built for dependable power distribution. Equipped with SF6 gas insulation, it provides outstanding arc-quenching performance, low maintenance requirements and high safety even in limited spaces. Supporting both ring-main and radial network configurations, this modular RMU allows flexible grid integration and can be installed indoors or outdoors. It effectively blocks external contamination to extend service life and reduce operation risks. Compliant with IEC and IEEE standards, it delivers stable performance under harsh conditions, widely adopted in urban power grids, industrial facilities and renewable energy projects.
