Xizi Energy’s SF₆ fully insulated gas load break switch is a core component for 10kV/24kV medium voltage (MV) ring main units (RMUs), designed for reliable power distribution in substations, renewable energy projects, and industrial grids.
This 3-position SF₆ switch integrates circuit making/breaking, isolation, and grounding in a sealed SF₆ gas chamber, delivering exceptional safety, reliability, and environmental adaptability for modern power systems.
Integrates three critical functions—load switching, isolation, and safety grounding—in a single compact unit, eliminating the need for separate grounding switches and simplifying RMU design.
The entire active part is enclosed in an epoxy resin-sealed SF₆ gas chamber, leveraging SF₆’s superior insulation and arc-quenching properties to ensure stable operation in harsh environments (high humidity, dust, altitude, and condensation) with minimal maintenance.
Engineered for seamless replacement and retrofitting of Schneider, ABB, Siemens and other international brand RMU switch units, making it ideal for grid modernization and old equipment upgrades.
Integrated modular structure reduces the overall size of the ring main unit, saving valuable substation space while maintaining full electrical performance.
Equipped with a temperature-compensated SF₆ gas density gauge for real-time pressure monitoring, with clear color-coded zones (green = normal, red = alarm) to prevent gas leakage risks.
Mechanical interlocking between the 3 positions prevents incorrect operation, ensuring maximum safety for maintenance personnel and grid reliability.
