15 FAQs about Sulfr hexafluoride Gas and Sulfr hexafluoride Breakers - WIKA blog

In a dry environment, SF 6 can quickly break apart to capture free electrons, and then recombine. However, when moisture enters a breaker, the sulfur and fluorine molecules grab water’s oxygen molecules to form byproducts during high-temperature episodes. One result is that there is now less of the gas to act as insulator.
