Unit substation | unit substation transformer | Eaton example, the close-coupled design allows the transformer and electrical equipment to be located in close proximity to the load concentration, which minimizes the lengths of cabling and buses to reduce power losses and exposure to faults. This close-coupled design can also improve voltage regulation and service continuity.
SF6 gas in medium-voltage switchgear | T&D Guardian ... is also used in gas-insulated substations (GIS) and gas-insulated lines (GIL), highly suited to urban power transmission applications. In the medium-voltage realm (up to 38kV), SF6 has been used outside the United States for circuit breakers having relatively low interrupting ratings.
