Abstract

This disclosure relates to an insulation system (1 1) for a winding structure (11). The insulation system (1 1) comprises an innermost barrier pair (3) arranged to cover a majority of the winding structure (11) in the axial direction (A) of the winding structure (11) inside and outside the barrier structure (11) relative the curvature of winding turns of windings of the winding structure wherein at least one barrier of the innermost barrier pair (3) defines a first flow path (3 1) allowing flow of a dielectric fluid (F) mainly in a first axial direction between the winding structure (11) and the at least one barrier when the insulation system (1 1) is in a assembled state; and a first outer barrier (5) arranged radially inwards or radially outwards relative each barrier of the innermost barrier pair wherein the first outer barrier (5) defines a second flow path (5 1) parallel to the first flow path (3 1) allowing flow of a dielectric fluid (F) mainly in a second axial direction opposite the first axial direction wherein the insulation system (1 1) is arranged such that a dielectric medium (F) is able to flow from the second flow path and enter the first flow path (3 1) at one axial end portion of one of the barriers of the innermost barrier pair (3) and at the other axial end portion of one of the barriers of the innermost barrier pair (3) exit the corresponding first flow path (3 1) wherein each barrier of the innermost barrier pair (3) has a contiguous envelope surface extending between the one axial end portion and the other axial end portion of each barrier of the innermost barrier pair (3). It is also presented an inductive device in which the insulation system (1 1) is arranged.
