  • gis substation Liquefaction System cost

    The concept of the gas insulated substation was introduced in 1920 when oil was used as the insulating medium in the system. A substation is considered as one of the vital element of power system infrastructure. Presently there are two types of substations primarily being used: Air Insulated Substation (AIS) and Gas Insulated Substation (GIS).
