Nov 28,2025
Gas-Insulated Switchgear is an advanced electrical equipment solution that uses insulating gas—typically SF₆ or eco-friendly alternatives—to achieve compact structure, high reliability, and superior safety performance. Compared with traditional air-insulated switchgear, GIS offers significantly higher system stability and reduced maintenance needs, making it ideal for critical power environments.
🌐 Why Choose Gas-Insulated Switchgear?
1. Compact Footprint, Maximum Efficiency
GIS can reduce installation space by up to 70% compared with conventional AIS structures. This is especially valuable for urban substations, high-rise buildings, industrial parks, offshore platforms, and mining sites where space is at a premium.
2. High Reliability and Enhanced Safety
All conductive components are fully sealed in metal enclosures filled with high-insulation gas. This design eliminates dust, humidity, and external contamination risk, ensuring extremely low failure rates and stable long-term operation.
3. Compliance With Global Standards
Our Gas-Insulated Switchgear solutions strictly follow:
IEC 62271-203
IEC 62271-100 / 200
GB/T 11022
These standards guarantee safety, durability, and international compatibility across various grid applications.
4. Superior Environmental Resistance
GIS delivers excellent performance under extreme environmental conditions, including high altitude, heavy pollution zones, seismic regions, and marine climates. The sealed structure ensures zero external influence, offering reliable operation for 30+ years.
5. Advanced Monitoring & Low Maintenance
With built-in digital sensors, automated diagnostics, and intelligent status tracking, GIS reduces manual maintenance by over 40%, minimizing downtime and operational risks.
🏢 Brand Strength: Global Expertise, Proven Quality
With over 25 years of industry experience, our company has delivered high-voltage GIS solutions to more than 60 countries, serving sectors such as:
