Core Advantages of SF6 GIS Switchgears
Fully Sealed Stainless Steel Gas Tank, Strong Environmental Adaptability: All live parts are sealed within a 3 mm non-magnetic anti-corrosion stainless steel SF6 gas tank. The gas tank forms a closed pressure system with working pressure of 0.15~0.4 bar. A pressure relief device is installed to release gas safely during overpressure. The unit is not affected by humidity, dust and salt fog, and supports maintenance-free long-term operation.
Reliable Mechanical Interlock, Prevent Misoperation: The load switch adopts coaxial rotating dual-break design. Through interlock of operating shaft and sliding plate, the switch can only stay in one state among close, open and earth at any time. The operating mechanism is mounted outside the gas tank with anti-corrosion treatment. Both manual and electric operation are available for convenient local control and remote automation upgrade.
Modular & Expandable Structure, Intelligent Upgrade Available: Modular bay design with two optional types: non-expandable standard configuration and expandable standard configuration. Expandable fully insulated shielded busbars allow flexible combination of incoming, outgoing and metering bays. It supports TVC intelligent automation solutions, reducing site installation and commissioning workload for smart distribution network projects.
