Abstract
A non-liquid immersed transformer includes a magnetic core and a coil winding forming a plurality of winding turns around the magnetic core; a cooling system and a first conductive connector. The cooling system includes a cooling pipe for the flow of a cooling fluid, the cooling pipe extending along the coil winding and including a first point adjacent to a turn of the coil winding, and a second point adjacent to another turn of the coil winding. The conductive connector is arranged at one of the first and second points, to electrically connect an inner side of the cooling pipe with a turn of the coil winding.
