Abstract (en)

[origin: EP2518739A1] The invention relates to the insulating casing of a high-voltage winding applicable in high-voltage electric power equipment in which metal conducting elements are embedded in resin insulation, and in particular it relates to the casing of a dry transformer winding. The insulating casing according to the invention is characterized in that it comprises a side strip (2) situated longitudinally on the circumference of a thick-walled cylinder (1), which strip has recesses (5) situated on the external surface of the side strip (2) between phase connection surfaces (3) and a tap connection surface (4). The recesses (5) can have transverse convexities (7) or longitudinal convexities (8) situated on the surface of the side strip (2) in the location of the recesses (5).
