Siemens sulfur hexafluoride fittings in Switzerland
Siemens sulfur hexafluoride fittings in SwitzerlandTen years later, the Siemens puffer circuit breaker brought the second generation of SF 6 circuit breakers onto the market. The modular system used in all Siemens SF 6 circuit breakers ensured very reliable operation and easy maintenance. These circuit breakers used sulfur hexafluoride (chemical formula: SF 6) as the arc quenching medium. It was blown onto the contacts and interrupted the arcs caused by switching.

how to harmlessly process SF6 maintenance in Syria
how to harmlessly process sf6 mix in Gabon 1. A process for separating a mixture of SF 6 and nitrogen or air, said process comprising: contacting the mixture in at least one adsorption stage with hydrophobic zeolites having an SiO 2 /Al 2 O 3 ratio of at least 80 and a pore diameter of 4 to 7 Å (0.4 to 0.7 nm) to preferentially adsorb SF 6, and recovering nitrogen or air depleted in SF 6.
GE sf6 Separating Recovery in Slovakia
GE sf6 Separating Recovery in SlovakiaIn SF6 circuit breakers, the same principle is employed, with SF6 as the medium instead of air. In the "puffer" SF6 breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of SF6 breakers have been developed for EHV (extra high voltage) transmission systems.
