The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The present invention relates to winding (10) of a dry-type transformer (80) configured to be arranged to surround a core (82) of the transformer (80). The winding (10) includes a first winding portion (16A), a second winding portion (16B), and at least one third winding portion (16C) which each include an electrically conductive material. The winding includes a first gap (20A) which is arranged between the first winding portion (16A) and the second winding portion (16B) and which is filled with electrically insulating material (22), at least a second gap (20B) which is arranged between the second winding portion (16B) and the third winding portion (16C) and which is filled with electrically insulating material (22), and a plurality of cooling channels (24) configured to guide a cooling medium therethrough to transfer heat from the transformer (80) to the cooling medium. The plurality of cooling channels (24) include a first cooling channel (24A) arranged within the first gap (20A) and a second cooling channel (24B) arranged within the second gap (20B). The first cooling channel (24A) and the second cooling channel (24B) each include a medium inlet (28) for introducing the cooling medium into the respective cooling channel (24) and a cooling medium outlet (30) for allowing the cooling medium to exit from the respective cooling channel (24). The cooling medium inlets (28) and the cooling medium outlets (30) are arranged in a side wall (34) of the transformer (80) and/or a side wall (34) of the winding (10). The present invention further relates to a transformer (80), a method of manufacturing a winding (10) of a transformer (80), and a method of operating a transformer (80).
