sf6 gas Separating separating unit for railway

sulfur gas isotope separation is proposed for the com­ parison among the different methods of the theoretical predictions. Further, the centrifugal separation for stable isotopes has recently been focussedC8l-C11 l, because a recent ultra high speed centrifuge enables one to separate gas iso­ topes with considerably light mass.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF 6 gas is electronegative and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of sulfur hexafluoride gas, and an arc is struck between them.
