Highly sensitive SF6 insulated testing

Introduction to GilTechnical DataHigh em CompatibilityGIL systems are based on the successful SF6 tubular conductor technology, which has been around for several decades. GIL consist of a central aluminum conductor with a typical electrical cross section of up to 5,300 mm2. The conductor rests on cast resin insulators, which center it within the outer enclosure. This enclosure is formed by a sturdy aluminum tube, which provides a solid mechanical and electrotechnical containment fo…See more on electrical-engineering-portalSF6 DownloadsEnvironmental XPRT gas-2021The 973- SF6 is an advanced SF6 gas analyzer for the measurement of humidity, SF6 purity and SO2 concentration in SF6 gas insulated switchgears (GIS) and other high voltage equipment.

    Advantages of sulphur hexafluoride in gas-insulated switchgears. SF 6 insulation allows safe operation of high- and medium-voltage systems in close areas, since insulation with sulphur hexafluoride requires much smaller safety clearances. Non-dispersive infrared gas sensors (NDIR sensors) from smartGAS are ideal for measuring the SF 6 gas quality and for detecting even very small quantities of the harmful gas.
