The present disclosure relates to a wound electrical component comprising a wound body comprising a plurality of wound layers of a web of an electrically insulating material around a longitudinal axis of the body. The wound body comprises a plurality of electrically conducting layers of an electrically conducting material, each printed onto a respective separate area of the web in the wound body. An edge zone of at least one of the plurality of electrically conducting layers is connected to a printed high permittivity layer of a high permittivity material along said edge zone such that at least a part of the high permittivity layer extends, printed on the web, beyond the edge zone.

Wound electrical component with layers of a high permittivity material

A high voltage capacitive device having: a non-impregnatable film having a plurality of physically separated regions each defined by a conductive coating provided on the non-impregnatable film, wherein the non-impregnatable film is wound in a plurality of turns to form a plurality of layers, wherein the regions are arranged in overlapping layers in the radial direction, wherein the non-impregnatable film forms a dielectric between adjacent layers of the regions, and wherein the conductive coating of at least some of the regions is provided with a plurality of first radial openings extending through the conductive coating to the non-impregnatable film, which delimits a radial extension of each first radial opening.
