The invention provides a stereoscopic wound core dry-type transformer for a subway. The stereoscopic wound core dry-type transformer for the subway comprises a wound core and a coil winding winded onthe wound core. The coil winding comprises coaxially winded high-voltage winding and low-voltage winding. Through breaking through the tradition, the high-voltage winding is installed at the inner side of the low-voltage winding, so the low-voltage winding is conveniently positioned at the outer side of the transformer, a safe distance of the outer side of the whole transformer is greatly reduced,and the safe and maintenance distance is reduced by 50% or more, thereby a design of a device room in an electric power substation is more compact and economic, and the stereoscopic wound core dry-type transformer for the subway is beneficial to reduce the occurrence of a safety accident.
