Product details
Model Number: GYJ-0051-#0958 Brand Name: GAOYAN Key Specifications/Special Features: New vacuum breaker from China, supply 2017LW24-40.5/72.5T, HVAC dead tank type SF6 gas circuit breakers is a new kind of circuit breaker with self-blast interrupter and spring operating mechanismOn the basis of technology of product imported from Mitsubishi, JapanLatest achieve- arc extinguishing principle of gas-blast pressure adapting with breaking-current is employed, by which most of energy required for breaking rated for short-circuit current are acquired from arc itselfTherefore, the demand for operating power is reduced significantlyThree pole interrupters are placed inside three metal enclosures respectivelyCircuit breaker can be mechanically three-phase gang operatedBoth remote electrical control and local manual control can be realizedType CT20-Ⅱ spring operating mechanism, provided with the product, is a kind of mechanism with low operating power, minimum maintenance work needed and high reliability
Product reaches international advanced level in the respect of main technical performance
