Winding, a transformer and a transformer arrangement

A winding for a phase winding of a transformer, said winding having coil turns around a coil axis, the winding having a first end and a second end and a winding center point on the coil axis between the first end and the second end,

• wherein the winding comprises a plurality of winding portions arranged along the coil axis said plurality of winding portions comprising a first winding portion arranged at the first end of the winding and a second winding portion arranged at the second end of the winding, the winding further comprising at least a third winding portion arranged along the coil axis between the first winding portion and the second winding portion, wherein the first winding portion and the second winding portion have a first winding portion stiffness as seen along said coil axis and the at least third winding portion has a second winding portion stiffness as seen along said coil axis, and wherein the second winding portion stiffness is greater than the first winding portion stiffness, and
• wherein the third portion has a third portion center point on the coil axis, equidistantly spaced at a distance from the first winding portion and from the second winding portion, which third portion center point is located closer to the first end of the winding than the winding center point.
