detecting abb sf6 circuit breaker catalog Australia,SF 6 sf 6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 gaz sf6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.
[email protected]A circuit breaker in which sf6 gas under pressure gas is used to extinguish the arc is called sf6 gas circuit breaker. insulating gas (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The insulating gas circuit breaker is mainly divided into three types

Get PriceThe production of VCB is not economical when designed in small quantities. The price of the breaker becomes too much at higher voltages. That's because high voltages more than 2 numbers of the circuit breaker are needed to be linked in series. The main drawback of VCB is that it is not economical, exceeding 38 kVolts.
