Gas density of Sulfr hexafluoride and other gases

Gas Density Sulphur hexafluoride (Sulfr hexafluoride) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe ­power distribution systems even in large cities. The insulation strength depends basically on the gas density.

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Where is Sulfr hexafluoride used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is sf 6 a health hazard? Pure sf 6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is sf 6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of Sulfr hexafluoride used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).

Sulfr hexafluoride circuit breaker maintenance | TD Guardian Articles

The first generation of sf 6 circuit breakers was the lower voltage classes of 72kV and 145kV. As sf6 gas breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing sf6 gas as the line-to ground dielectric insulation.

What is insulating gas Circuit Breaker? Construction, Working Principle

SF 6 gas is extremely stable and inert, and its density is five times that of air. It has high thermal conductivity better than that of air and assists in better cooling current carrying parts. SF 6 gas is strongly electronegative, which means the free electrons are easily removed from discharge by the formation of negative ions.

All About Togo - Africa.com

HistoryEconomyGeography and ClimateAdministrative DivisionsDemographicsEthnic GroupsReligionLanguagesHealthEducationBetween the 11th and 16th centuries various tribes such as those from Ghana and Nigeria entered the region with most settling in the costal areas. For the next two hundred years the coast became a major center for European slave trade and earned Togo and the nearby areas the reputation as “ The Slave Coast.” The Mina from Ghana were the most victimized by the slave trade. In 1884 Germany signed a treaty at Togoville under the King Mlapa III, which declared Togoland a protectorate that stretched from the coast inland. This became the German colony of Togoland in 1905. After Germany was defeated in World War I, Britain and France administered Togoland as two League of Nations mandates. The mandates became UN Trust Territories after World War II. British Togoland joined the Gold Coast, which in 1957 became the independent nation of Ghana. In 1959, French Togoland became an autonomous republic of the French Union until its independence in 1960. Slyvanus Olympio brought independence to T...
