Product description

Product Overview
The Live Tank SF6 Circuit Breaker is a high-performance outdoor switching device designed for protecting and controlling 110kV electrical networks. It is the most economical and reliable choice for large-scale outdoor substations due to its lightweight structure and superior arc-extinguishing capabilities.
Key Features
High Breaking Capacity: Engineered with advanced SF6 interrupters to ensure rapid arc extinction and a high short-circuit breaking current of up to 40kA.
Superior Mechanical Life: Tested for over 10,000 operations (M2 class), ensuring long-term reliability in high-frequency switching environments.
Lightweight & Economical: The live tank design minimizes the use of heavy materials, significantly reducing the cost of steel support structures and civil foundations.
Low Maintenance: Features a Hermes-sealed gas system and high-quality SF6 insulation, requiring minimal oversight throughout its service life.
Global Compliance: Fully complies with IEC 62271-100 and ANSI/IEEE international standards for safety and performance.

FAQ
1. What are the primary advantages of a Live Tank design compared to a Dead Tank?
The Live Tank structure is significantly more lightweight and compact, which reduces the cost of civil foundations and steel support structures. It is generally the most economical choice for large-scale outdoor substations where space and budget efficiency are priorities.
2. How does the breaker ensure reliable performance in extreme weather conditions?
Our breakers feature a weather-resistant design with a C5M anti-corrosion rating, making them suitable for coastal or high-pollution areas. Additionally, the Hermes-sealed gas system prevents moisture ingress, ensuring stable insulation even in high-humidity or high-altitude environments.
3. What is the expected maintenance cycle for this SF6 circuit breaker?
Due to the high-quality SF6 insulation and the M2 class mechanical endurance (10,000 operations), the unit requires very low maintenance. Routine inspections are typically limited to checking the SF6 gas pressure gauge and the condition of the operating mechanism.
4. Can this breaker handle high-frequency switching for renewable energy projects?
Yes. The 10,000-cycle mechanical life rating makes it ideal for solar and wind power plants, where frequent grid-connection switching is often required.
5. Does the equipment comply with international safety standards?
Absolutely. The breaker fully complies with IEC 62271-100 and ANSI/IEEE standards, ensuring global compatibility and meeting the rigorous safety requirements of major utility companies.
6. What is the standard lead time for a 110kV order?
By leveraging our six production sites and modular manufacturing process, we offer a fast delivery cycle of approximately 30 days for standardized configurations.
7. Is technical support available for installation and commissioning?
Yes. As a strategic partner to global energy firms, we provide 24/7 service response and integrated technical support, including guidance on site-specific mounting and protection schemes designed by our R&D team.
