Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.

TIDO SERIES – ONLINE TRANSFORMER INSULATION DRYING ... HERING TIDO® online transformer dryer uses a vacuum process to continually remove moisture and gas from the transformer oil. This creates a water content gradient from the wet insulation to the dry transformer oil that causes a steady removal of water from the insulation paper.
