  • Separation of CF4/N2, C2F6/N2, and SF6/N2 Mixtures in

    The capture and separation of CF 4, C 2 F 6, and SF 6 and their mixtures containing nitrogen is a challenging process. To solve this, we propose the use of saccharose coke-based carbons as membranes for the adsorption and separation of these gases.

    Abstract: A dual photomultiplier system and a field probe have been used to study the optoelectrical phenomena in commercially pure SF6 and mixtures of SF6 with oxygen-free N2, under impulse voltages in a point-plane gap. The critical pressure has been estimated using an extrapolation technique, and the results have been compared with those of other recently published work.

  • Learn About Our Horizontal Circuit Switchers - Southern States

    The Southern States family of horizontal interrupter circuit switchers are ideally suited for transformer protection on systems with fault currents up to 40 kA. All circuit making and breaking operations are accomplished in SF 6, eliminating open air arcs. Designs are available with an integral vertical break switch (Types CSH-B or CSH2-B) or without (Types CSH or CSH2) and are extremely versatile, as they can be mounted in most orientations including horizontal upright and vertical.
