Product introduction
The Aierway 24kV Center Distance 310mm is an advanced fixed-assembly, solid-insulated switchgear specifically engineered for high-reliability 24kV applications. Its defining feature is the solid-sealed pole terminal design—where vacuum interrupters and main connections are permanently cast in epoxy resin—combined with a generous 310mm phase-to-phase center distance for superior dielectric performance and thermal management. This product is designed for mission-critical installations where maintenance-free operation, maximum safety, and long-term reliability are paramount.
Key Advantages of this Design
1. Zero Maintenance: No gas to monitor, no contacts to adjust, no insulation to clean.
2. Absolute Safety: Live parts are completely inaccessible during operation or maintenance.
3. Environmental Immunity: Unaffected by humidity, pollution, altitude, or temperature variations.
4. Exceptional Durability: Solid construction resists vibration, mechanical shock, and thermal stress.
