Introduction: Why Air Insulated Switchgear Matters Today
In modern energy distribution, air insulated switchgear (AIS) has become a preferred choice for industries seeking safety, reliability, and cost efficiency. While competitors such as Siemens, ABB, and Schneider Electric dominate the market, Dongshengyuan stands out by delivering affordable, practical, and globally certified AIS solutions designed for real-world applications.
What is Air Insulated Switchgear (AIS)?

How It Works
Air insulated switchgear uses ambient air as the insulation medium between live electrical components. Unlike gas insulated switchgear (GIS), which relies on SF6 gas, AIS is simpler, safer, and environmentally friendly.
Key Features and Benefits
- Lower cost compared to GIS
- Easy maintenance with accessible parts
- Environmentally safe—no greenhouse gases
- Flexible designs for both indoor and outdoor use
Air Insulated Switchgear vs Gas Insulated Switchgear

Cost and Investment
AIS is more affordable for medium- and low-voltage systems, while GIS often requires higher upfront investment.
Safety and Reliability
AIS ensures high safety margins with robust insulation, making it a strong choice in open industrial environments.
Maintenance and Serviceability
AIS is easy to service, with no need for specialized gas handling equipment required for GIS.
Environmental Impact
AIS is a green solution—unlike GIS, which depends on SF6 gas, one of the most potent greenhouse gases.
