Claims (1)

[Scope of utility model registration request] In a transformer housed in a sealed container and filled with insulating gas, there is a low-voltage winding wound concentrically with the iron core, and a high-voltage winding distributed and wound in multiple groups around the outer circumference of the low-voltage winding. , disposed between the low-voltage winding and the high-voltage winding so as to span a plurality of high-voltage windings, both ends protruding from both ends of the high-voltage winding, and the innermost layer of the plurality of groups of high-voltage windings. A gas insulated transformer including an electric field mitigation shield that is connected to the line ends and also serves as a conductive path between the high voltage windings.
