  • Thermal Decomposition Properties of Epoxy Resin in SF6/N2 Mixture

    As a promising alternative for pure SF 6, the mixture of SF 6 /N 2 appears to be more economic and environment-friendly on the premise of maintaining similar dielectric properties with pure SF 6. But less attention has been paid to the thermal properties of an SF 6 /N 2 mixture, especially with insulation materials overheating happening simultaneously.

  • SF6 gas Mixtures Management discount

    SF6 gas Mixtures Management discount N2 / SF6 gas mixtures (5 – 10 % by volume of SF6) are employed to refine pure Aluminum or its alloys at melt temperatures in the range 650 – 750 C. SF6 is a source of fluorine atoms reacting in the melt and removing inclusions of H2, oxides, particles and other casting impurity.

  • Thermal Decomposition Properties of Epoxy Resin in SF6/N2 Mixture

    The results showed that thermal properties of 20% SF 6 /N 2 (volume fraction of SF 6 is 20%) mixture has faster degradation than 40% SF 6 /N 2 mixture. As ratio of SF 6 content decreases, thermal stability of the system decreases, and the decomposition process of SF 6 is exacerbated. Moreover, a mathematical model was established to determine happening of partial overheating faults on the epoxy resin surface in SF 6 /N 2 mixture.

  • 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.
