Main Technical Parameters

Core Product Technologies

1. First Generation: Air Insulation

First-generation vacuum circuit breakers had their live parts completely exposed to air. Insulation levels were easily affected by external factors such as environmental humidity, dust, and transportation vibrations. They were also susceptible to interference from small animals and other foreign objects, posing safety hazards and resulting in poor operational stability.

2. Second Generation: Composite Insulation

Second-generation products used epoxy resin bushings to protect the arc-extinguishing chamber, improving insulation performance to some extent. However, the bushings did not completely enclose the high-voltage live parts, leaving them still susceptible to environmental factors such as dust, moisture, and insects, limiting long-term operational reliability.

3. Third Generation: Solid-Sealed Insulation (Usune Core Technology)

The Usune Vs1 Vacuum Circuit Breaker uses third-generation solid-sealed poles. Through advanced APG (Automatic Pressure Gel) technology, high-performance epoxy resin is used to encapsulate the arc-extinguishing chamber and the upper and lower outgoing terminals as a whole. Key advantages include:
- Complete isolation from the external environment, unaffected by dust, moisture, insects, etc., significantly improving the product's weather resistance and adaptability to harsh operating conditions, ensuring stable operation in various complex indoor scenarios.
- Optimized structure: Epoxy resin serves as both primary insulation and mechanical support, reducing the volume of the arc-extinguishing chamber while enhancing structural stability.
- Superior electrical performance: Electric field and stress distribution are superior to various irregularly shaped insulating partition structures, effectively reducing the risk of insulation breakdown and improving overall electrical performance and service life.
