  • Gas-insulated Switchgear Market Revenue to Hit $26.5 Billion

    Mar 31, 2021 · SF6-filled gas-insulated switchgears are preferred over air-insulated switchgears where space is a constraint because air-insulated switchgears require meters of air as an insulation medium to do what SF6-filled switchgears can do in centimetres. Therefore, SF6-filled gas-insulated switchgears can be 10 times smaller than air-insulated switchgears.
