As a suburban or rural substation overhead line switching control and protection

Easy to install and operate the pole circuit breaker. Mainly for urban overhead distribution lines segmented interval switching control and protection. Suburban or rural areas can also be used as an overhead line substation control and protection switching.  Voltage stabilizer  to oil-immersed  electric meter  breaking ability, oil inflammable, causing secondary disasters tend to be eliminated. After the 1980s, the use of SF6  power transformers  device with excellent performance, since the 1990s, began to adopt further operating power, long life of the vacuum interrupter. Typical pole breaker main technical parameters: Rated voltage 12kV, rated current 400,630 A, rated breaking current 6.3.
