    Open Air SubstationsMetal EnclosedMetal-CladGas-Insulated SubstationsOpen air substations contain separately mounted and interconnected switching equipment and components, like current transformers (CTs), voltage transformers (VTs), busbar support insulators, cable sealing ends, etc., where atmospheric air provides the main insulation path to earth. This is very important requirement and it requires relatively large clearancesand, in consequence, open-air substations tend to cover large ground areas. Also, if substation is located near local communities, they’re usually not very happy about its location. Some degree of landscaping is normally required to minimize the visual impact.
