Transformer arrangement

A transformer arrangement comprising

• a transformer comprising at least one phase winding, said phase winding having coil turns around a coil axis, the transformer having a first extension along a first axis parallel with the coil axis, a second extension along a second axis and a third extension along a third axis, said first, second and third axes being perpendicular to each other, and wherein the transformer has lateral sides parallel with the coil axis,
• a transformer tank having walls forming an enclosure in which said transformer is arranged, said enclosure containing an incompressible medium in which the transformer is immersed,
• a screen arranged in said transformer tank, between the walls of the transformer tank and the at least one phase winding of the transformer, said screen having an inner, transformer-facing, surface and an outer, wall-facing, surface, and
• wherein the screen is arranged distanced from the at least one phase winding of the transformer, in that the screen has at least two lateral parts aligned with the lateral sides of the transformer, and wherein each of the at least two lateral parts of the screen comprises a continuous band that circumscribes the transformer and the at least two lateral parts have a height along the first axis, a sum of the individual heights being equal to, or less, than a height of the at least one phase winding.
