As a trusted EHV Dead Tank SF6 Circuit Breaker China Manufacturer, ROCKWILL offers OEM/ODM customization services. In the development history of China’s dead tank SF₆ circuit breaker industry, we are undoubtedly a pioneer. As an original manufacturer focusing on this sector, decades of technical accumulation and continuous innovation have laid a solid foundation for mature production and kept us at the forefront of R&D. Our products exceed market expectations in reliability and are the preferred choice for numerous major power projects.
High Voltage Rating Adaptability: Specifically designed for 363 kV extra-high voltage systems, it stably handles high voltages and large currents, ensuring reliable operation of EHV transmission lines.
Efficient Arc Extinguishing Performance: Using SF6 gas as the arc-extinguishing medium, it features fast arc extinction and high insulation strength, quickly cutting off fault currents and minimizing system impacts.
Dead Tank Sealed Structure: The dead tank design encloses live parts in a metal tank filled with SF6 gas, effectively isolating them from the external environment. It offers strong seismic resistance and adapts to harsh climates and complex geographical conditions.
Long Lifespan & Low Maintenance: With long mechanical and electrical lifespans, the sealed structure reduces component aging and external erosion risks, minimizing maintenance frequency and operational costs.
Multifunctional Integrated Design: Integrates components like inlet/outlet bushings and current transformers, enabling multiple functions such as current measurement, protection, and circuit switching to meet complex control needs of power systems.
High Safety Assurance: Equipped with comprehensive anti-misoperation interlocking devices and multiple insulation protections, it effectively prevents operator errors and ensures the safety of personnel and equipment.
