advantages of sf circuit breaker United Kingdom,Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay.Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.

sf6 gas Gas Servicing Equipment. Sulfur Hexafluoride (sf 6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgear employed by the power industry. Applications for sf6 gas include gas insulated transmission lines and gas insulated power distribution

750kv abb sf6 circuit breaker spares Egypt,IEC outdoor gas insulated (sf6 gas) circuit breaker OHB Medium Voltage circuit breaker with mechanical operating mechanism designed for distribution systems up to 40.5 kV, 2500 A, 31.5 kA. These circuit breakers are of live tank design.

Properties of insulating gas (Sulfur Hexafuoride) GasHandling Nonfaulted sf6 gasHandling Faulted Sulfr hexafluorideDisposal of Wastea) Toxicitysf6 gas is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. If the normal oxygen content of air is re­duced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks shob) Toxicity Of Arc ProductsToxic decomposition products are formed when Sulfr hexafluoride gas is subjected to an elec­tric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs. Do not breathe the vapors remaining ic) Physical Propertiesinsulating gas is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. sf 6 shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically than air.
