Advantages Of Sealed Pole Type

1.Embedded Pole High reliability: The internal vacuum circuit breaker design eliminates impurities in the air, reduces the possibility of flashover and breakdown caused by instantaneous overvoltage, and greatly improves the stability and safety of operation. In addition, the vacuum circuit breaker has a strong arc extinguishing ability, which can effectively isolate the fault point and ensure the normal operation of the power system.
2. Simple maintenance: There is no wearing part inside. Compared with traditional air circuit breakers, it does not need to maintain and replace carbon brushes, springs and other wearing parts frequently. It only needs to regularly check the state of the mechanical part, check the flexibility of the operating mechanism, and perform necessary cleaning and lubrication. This can not only save maintenance costs, but also save time and human resources.
3. Simple structure: It has a modular design, fewer detachable parts, fewer overlapping surfaces of conductors, and fewer connecting bolts, which makes the structure simple and greatly improves the reliability of the circuit breaker.
4. Strong insulation rod capacity: Surface insulation is converted into volume insulation, which reduces the impact of the environment and greatly improves the insulation strength compared to air insulation.
