SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

Features. Even in the event of a complete gas leak, our SF6 CBs are capable of breaking 100% normal current with stand system voltage. Advance warning of gas leak by continuous pressure monitoring. Explosion proof and fail safe CB by means of safety membrane for each pole. Automatic safety shutters to cover live parts when CB is withdrawn.
sf6 vessel manufacturer price
sf6 vessel manufacturer priceA Gas Insulated Substation (GIS) is defined as a high voltage substation in which the main structures are confined in a sealed environment with sulfur hexafluoride gas as the insulating medium. A gas insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase to phase and phase to ground insulation.
