Sulfr hexafluoride gas in medium-voltage switchgear | TD Guardian Articles

Sulfr hexafluoride has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses sf6 gas gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

sf6 gas circuit breaker maintenance | TD Guardian Articles

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

density

Density, or the volumetric mass density, of a substance is its mass per unit volume. Its symbol is ρ (the lower case Greek letter rho). In some cases, density is defined as its weight per unit volume, such as the United States oil and gas industry - that quantity is more specifically called specific weight.
