Underground substations – Out of sight, out of mind
Underground substations help to bring high voltage electricity directly into the city center. The stations are environmentally friendly, almost unnoticeable, and have none of the planning problems encountered by surface-built solutions. Building new transformer substations in inner-city zones or expanding… Read more
