Introduction     

Now, most of the 72.5 breaker use SF6 as the insulating method, but it is easy to pollute the environment and it will liquefy under -25℃, at that time, it will lose the function of insulation, thus bringing a tremendous trouble on the environment and electricity production and running.

Our company has independently developed the 72.5 Outdoor Intelligent optional high voltage permanent magnetic vacuum breakers, with the new design and high technology. This breaker has permanent magnetic mechanism, vacuum, arc extinction, integrated sensor, ARM and DSP processor. It can auto adapt to the effects of parameters and environmental factors. By the contact IEC61850, it can meet the needs of the smart grid and the environment. Therefore it is the device of choice for intelligent network.
