Product Description
7.2kV -1600A VMV vacuum circuit breaker


7.2kv -1600A Vmv Vacuum Circuit Breaker

VMV Circuit Breakers' Embedded Poles
 
       VMV circuit breakers adopt the second generation embedded poles, through advance APG technology, the lowresistance vacuum interrupter and main conductive circuit parts are sealed in epoxy resin, greatly simplify the assembly process, lower the circuit's resistance, and improved the stability.  
       

       What's more, Vacuum interrupter is sealed in with epoxy resin material, guaranteed the minimized affection from external environment, and its external insulating ability will avoid the influence from dust, moisture, small animal, condensation and filthy, fully satisfy requirements of GB/IEC standards of creep distance in secondary filthy area.


Technical Innovation

         VMV circuit breakers' overall structure is optimize base on traditional VCB, with more simple structure .What's more, all VMV circuit breakers' operating mechanism are standard and compatible, so great reduced  users' equpments maintenance cost. 

         Modularized design of operating mechanism is VMV vacuum circuit breaker' shighlight,   opening module and closing module are in one part, can separate from mechanism'    other parts, so convenient to maintain, quick to exchange ,  and  with short power cut for repaing.   What's more  manufacturer's prodution effciency is much more higher.


Gear Driving System

       Fully Automatic Production Assembly Line VMV circuit breaker's assembly line is designed and produced by ourselves, according to our actual production need   and  circuit breakers' technical features.  Every production process is controlled and monitore computer .Thank you for automatic line, our products increased greatly,  up to 22000 piece per year.

Packaging, Transportation and Storage Precautions
 

(1) Circuit breaker should be in the state of opening and energy storage spring in a state without energy storage when packing. It should be in the state of opening and energy storage spring in a state without energy storage when packing. And it should be fixed on the bottom of the wooden case, should have waterproof measures and complete package labels.
(2) Circuit breakers can't invert and avoid strong vibration, rain, surface damage, and components lost when transportation.
(3) When loading the circuit breaker, we suggest the following tools: crane, forklift and driving. When lifting the circuit breaker, we should not hook on the body or pole of the circuit breaker, but on the lifting hole which has the lifting mark.
(4) When circuit breaker has a long-term storage, it should be in a state of opening and energy storage spring in a state without energy storage and placed in dry ventilated indoor preventing from moisture, vibration control and harmful gas erosion, and regularly checked whether environment meets the requirements.
(5)When first use products after long-term storage, it need to have a power frequency withstand voltage insulation testing.
