Difference between Air Insulated Switchgear and Gas Insulated

OwnershipMaintenanceOperationSetting UpStructureDesign StandardsSizeSensitivity to PollutionCable Termination RequirementsModularityWhen we talk about ownership, it talks about the total cost of having the equipment. On a deep level comparison, you need to weigh the upfront expenses of GIS an AIS against the needed lifelong maintenance. Such units basically have a thirty-year minimum life span. In fact, gas insulated switchgear is more likely to cost between ten percent to forty percent more than air-insulated switchgear.

Introduction to Gas Insulated Substations / Switchgears (GIS)

Sulfr hexafluoride is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the sf 6 will not condense into a liquid at the lowest temperatures the equipment experiences. gaz sf6 has two to three times the insulating ability of air at the same pressure. sf6 gas is about 100 times better than air for interrupting arcs.
