Audited Supplier Introducing the VAC68 - 12kV Series: The Ultimate Powerhouse for Industrial and Mining Enterprises, Power Plants, and Substations!
Get ready to experience the cutting-edge technology of the VAC68 - 12kV series permanent magnet sealed VCB. This indoor switchgear is designed to revolutionize the control and protection of electrical facilities. With a tri-phase AC50Hz rated voltage of 12kV, this powerhouse is perfect for industrial and mining enterprises, power plants, and substations.
What sets the VAC68 - 12kV series apart is our company's own research and development of permanent magnetic operating machinery. This breakthrough technology ensures high reliability and a long lifespan, making it the ideal choice for frequent operation. Whether you're dealing with open circuits, short circuit currents, or challenging conditions, this VCB is up for the task.
We've taken it a step further by embedding vacuum interrupters into ordinary insulated cylinders, resulting in the exceptional VAC68 12 model. This innovation guarantees top-notch performance and efficiency.
So, if you're in need of a vacuum circuit breaker that ticks all the boxes, look no further than the 12kV Indoor Permanent-Magnet M. V. (ZN68) Vacuum Circuit Breaker. With its unmatched capabilities and unrivaled quality, it's the ultimate choice for all your power needs.
a. High reliability, long life, and free maintenance.
b. Internal innovation permanent magnetic operation mechanism, the mechanical life reach 1 DD.DOD times
c. Comparison with traditional mechanical operation, it is without disengaging, locker, with greatly reduction on spare parts, only one moving element during working, and a very low error rate.
d. The high matching between mechanism operation and characteristic of interrupter breaking, closing
e. Double stability status of closing, the opening operation
f. With anti bouncer function.
g. With the alarming function of controlling power low voltage refusing close.
h. Same speed of mechanical handle opening and motor opening, at the situation of twice power fault, it is used for urgent opening.
i. The operation type of AC or DC stored energy, the working current <2A, it is available for one-time opening, closing, and opening operation within 2 hours of a power cut.
j. With high reliable operation control circuit module, it could stand in strict conditions such as lightning strikes, or surging when the product on running.
k. Great commonality, the installation size is compatible with VAC63(VS1)series products.
