Sulfr hexafluoride insulated Voltage Transformers – Trench Group

SF 6 insulated voltage transformers are used to convert high transmission line voltages (up to 800kV) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system. As such, the need for accurate and reliable voltage transformation is essential. The reliability and security of Trench gas-insulated instrument transformers is based on over 50 years of innovation with gas-insulated units operating under a wide range of

insulating gas (GIS) gas insulated substation Manufacturer in China

The gaz sf6 gas insulated substation (GIS) is assembled by several gaz sf6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of sf 6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could operate in stable condition for more than 30 years.

gaz sf6 gas as insulating and arc-quenching medium

Sep 20, 2011 · Sulphur hexafluoride gas (gaz sf6) is employed as insulation in all parts of the installation, and in the circuit-breaker also for arc-quenching. sf6 gas is an electronegative gas, its dielectric strength at atmospheric pressure is approximately three times that of air. It is incombustible, non-toxic, odourless, chemically inert with arc-quenching properties 3 to 4 times better than air at the same pressure.

sf 6 Transmitter - Draeger

When insulating switchgear or transformers, sulfur hexafluoride (Sulfr hexafluoride) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dräger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.
