  • Difference between Air Insulated Switchgear and Gas - Orecco

    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.
