In an era when reliability, safety, and sustainability define success in electrical infrastructure, the term Air Insulated Switchgear (AIS) stands as a symbol of innovation and trust.
At Dongshengyuan Electrical Equipment Co., Ltd. (DSY), we deliver cutting-edge AIS solutions that merge advanced engineering with internationally recognized standards — ensuring dependable performance across industries and continents.
Air Insulated Switchgear (AIS) refers to electrical switchgear that uses air as the insulating medium between live components and grounded or adjacent conductors.
Widely used in medium-voltage systems (up to 36 kV), AIS technology supports critical power networks — from utility substations and industrial plants to transportation hubs and commercial complexes.
Its simplicity, adaptability, and cost-effectiveness make AIS the most prevalent switchgear type globally, accounting for approximately 60% of the world’s medium-voltage market (source: Zoliov Power Analysis Report 2024).
⚙️ Why Choose AIS? – Core Advantages
✅ Cost-Effective & Easy Maintenance
Using ambient air as the insulating medium eliminates the need for costly SF₆-gas systems. Maintenance and inspection are straightforward, reducing lifecycle costs without compromising reliability.
🌱 Environmentally Friendly
Unlike gas-insulated systems, AIS contains no greenhouse gases, making it a greener solution that aligns with global carbon-reduction goals and sustainable infrastructure policies.
🔧 Flexible Configuration & Scalability
AIS modules are compact, customizable, and easy to expand — ideal for facilities expecting future load growth or system reconfiguration.
🛡️ Proven Safety & Reliability
Built to withstand harsh climates, modern AIS solutions are designed with IP-rated enclosures (up to IP67) for superior protection against moisture, dust, and temporary flooding.
⚡ DSY’s AIS Highlights
Our Air Insulated Switchgear line features a fully insulated and sealed modular design, ensuring operational reliability even in extreme conditions.
Key specifications include:
Protection rating: IP67 for main circuits
Operating temperature: –40 °C to +50 °C
Altitude tolerance: ≤ 4000 m
Humidity resistance: ≤ 90% monthly average
Flexible module combinations: Load Switch (L), Load Switch + Fuse (F), Circuit Breaker (CB), Busbar Disconnector (S), Metering (M), Busbar PT (PT)
These modular options make DSY’s AIS ideal for ring-main systems, transformer feeders, and industrial distribution networks worldwide.
🌐 Built to Global Standards
Every DSY AIS unit complies with the latest international standards, guaranteeing interoperability and safety across different regions and applications:
IEC 62271-1 and IEC 62271-200 for medium-voltage metal-enclosed switchgear
ANSI C37.20.2 for design, testing, and performance in North America
ISO-certified manufacturing and strict quality assurance throughout the production process
Compliance with both IEC and ANSI systems ensures our switchgear performs reliably in diverse markets — from Asia and the Middle East to Europe and the Americas.
🏭 Brand Strength & Real-World Application
With years of expertise in switchgear engineering, DSY stands as a trusted name in medium-voltage power distribution.
Our state-of-the-art manufacturing facilities, advanced testing systems, and experienced R&D teams enable us to produce world-class AIS with consistent quality and fast delivery.
🚀 Why DSY’s AIS Stands Out
Fully sealed & maintenance-free structure
Superior environmental protection (IP67)
Compact, modular, and easily expandable design
Global standards compliance (IEC, ANSI, ISO)
Proven field performance in harsh conditions
Sustainable and cost-efficient lifecycle
