GVSQ1-12~40.5kV series fully enclosed and insulated all working condition intelligent solid insulating vacuum circuit breaker is adopted the worlds' first fully enclosed structure and the fourth generation solid enclosed type which is the most advanced solid insulation technology. The products are solid
insulation embedded vacuum circuit breakers by real means and it also the only high-performance solid insulation embedded vacuum circuit breaker which can be apply for all working condition.
The product is adopt fully-sealed structure that can be completely separated the embedded poles with outside. Therefore, it will not effected by pollution or condensation. The moving contact arm is also adopted fully sealed structure so it product has better environmental adaptation and can be used for extremely weather. In real means, it has realized the maintenance-free for embedded poles.
The product meet requirement of standard National Standard GB1984-2003 and International standard IEC62271-100-C2-E2-M2, and other developed country's standards; The product adopted advanced solid insulation technology for externa insulation of arc-extinguish chamber. It is based on green, environmental protection and energy conservation.
GVSQ1 series fully enclosed and insulation all working condition intelligent indoor HV vacuum circuit breaker is our new circuit breaker of 12~40.5kV. It is intelligent products in order to suitable for intelligent power grid. It can be widely used for power plant, power grid, metallurgy, petrochemical industry and urban infrastructure construction etc.
