SF6 Gas Insulated Switchgear

SF6 Gas Insulated Switchgear is a high-voltage electrical equipment that uses sulfur hexafluoride (SF6) gas as an insulating and arc-extinguishing medium. Its core components (such as circuit breakers, disconnectors, busbars, etc.) are sealed in a metal casing filled with SF6 gas. The SF6 switchgear encapsulates all high-voltage parts in a gas tank, which not only ensures the safety of operators but also has moisture-proof and dust-proof functions, extending the service life of the equipment. TSTY's SF6 switchgear mainly has 6kV, 10kV, 15kV, 20kV, 33kV and other specifications, and is widely used in cities, industrial areas, power generation and transmission, data centers and factories.

1. Good insulation performance: SF6 gas has high insulation strength, which is more than three times that of air under the same pressure. It can effectively reduce electrical gaps and make the equipment structure more compact.

2. Strong arc extinguishing ability: SF6 has good arc extinguishing performance, which is 100 times that of air. It can quickly extinguish arcs, improve the breaking capacity and reliability of switchgear, and is suitable for occasions with frequent operations.

3. Small environmental impact: The sealed structure has the advantages of dustproof, moisture-proof, and anti-pollution, and can operate stably in harsh environments such as high altitudes and coastal areas.

4. Compact structure: The fully enclosed design saves space and occupies only 10%-30% of the air insulation cabinet, which is suitable for space-constrained areas (such as urban underground substations).

5. Low maintenance requirements: Sealed components reduce interference from external factors, have a long maintenance cycle, and are highly reliable.

6. Flexible configuration: It can be equipped with multiple load switches, flexible wiring methods, support multiple branch sockets, and a rich variety of accessories to meet various needs.

SF6 Gas Insulated Switchgear Application Scenarios

Urban power grid: dense urban areas, underground substations and other areas with limited space, using its compactness to optimize layout.

Special environments: industrial pollution areas, high humidity coastal areas, multiple earthquake zones and other places with high requirements for equipment reliability.

New energy grid connection: in the booster stations of wind farms and photovoltaic power stations, adapting to frequent operations and complex grid conditions.
