Abstract: The invention is related to a dry transformer (40), comprising a transformer core (10) with at least two parallel limbs (12, 14, 16, 58, 60, 62) and belonging upper (26, 28, 30, 42, 44, 46) and lower (20, 22, 24) yokes and at least two hollow cylindrical coils (32, 52, 54, 56, 112, 114), each arranged around a limb (12, 14, 16, 58, 60, 62). A cooling system comprising at least one wall-like diaphragm (74, 90, 102) in-between neighboured coils (52, 54, 56; 112, 114) is foreseen which is in parallel to the orientation of the limbs (12, 14, 16, 58, 60, 62).
