This product is mainly used in power system with rated voltage of 12 kV and rated frequency of 50-60 Hz. It mainly transmits electricity to power plants, small and medium-sized generators, industrial and mining enterprises, power distribution and electric industry. The secondary substation of t he system is controlled, protected and monitored for receiving, transmitting electricity and starting of large-scale high-voltage motor. The performance of this switchgear meets GB3906, IEC298 and other standards.Requirements, with the prevention of load push-pull circuit breaker handcart, prevent mis-breaking circuit breaker, prevent grounding switch in the closed position to close circuit breaker, prevent mis-entry into the live compartment, prevent in-band.The "five preventive" interlocking function of the grounding switch can be matched with the VD4- I 2 vacuum circuit breaker of ABB, which is a kind of distribution device with superior performance.
