GIS, ZF10-145(L)T3150-40

This newly designed GIS features a fully three-phase, shared-tank compact structure. Its circuit breaker utilizes a self-blast arc-extinguishing mechanism based on "thermal expansion + gas-assisted blowing" and is equipped with a CT26-type spring operating mechanism. Key advantages include high breaking capacity, short arcing time, a total breaking time of just three cycles, long electrical lifespan with up to 20 full-capacity breaking operations, a streamlined design, and exceptional reliability.
