dilo HV switchgear Insulating gas units

Dilo was the first company ever to deal with the problem of handling sulfur hexafluoride (SF6) back in the 1960s. Sulfur hexafluoride is used as an insulating gas in electrical switchgear. Dilo has developed technical solutions that prevent this climate-damaging gas from entering the Earth's atmosphere.

    SF 6 Free Gas Handling Alternatives to SF 6. The so-called Alternative Gases are alternatives to SF 6, the preferred insulating and arc-quenching gas used in switchgear in the last few decades.While SF 6 has excellent dielectric properties, it is also the most potent greenhouse gas with a GWP of 23,900. Ideally, SF 6 should be used in closed loop systems and never be emitted into the atmosphere.

    Oct 23, 2020SF 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas SF 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar. As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only SF 6 is used both for interruption medium and insulation.
