The invention relates to an HVDC air-core reactor (1) having at least two electric terminals. Said air-core reactor (1) comprises at least one hollow-cylindrical winding layer (2 - 2"), the electrical conductor wire (17) of which, together with its lateral-surface insulation layer (18), is wound helically around a reactor axis (14), and a charge dissipation layer (20) with a predefined electrical conductivity, which charge dissipation layer (20) is applied at least to an outer lateral surface (21) of the at least one hollow-cylindrical winding layer (2 - 2") and is electrically conductively connected to at least one of the electrical terminals of the air-core reactor (1). The charge dissipation layer (20) comprises at least one first strip element (23) consisting of electrically conductive material, which runs helically around the reactor axis (14) and bears against the outer lateral surface (21) of the at least one hollow-cylindrical winding layer (2 - 2"). The invention also relates to a method for producing such an HVDC air-core reactor (1). An HVDC air-core reactor is thus created with which undesired, field-strength-induced particle deposits can be avoided during active operation and which HVDC air-core reactor can still be constructed as cost-effectively and as functionally reliably as possible.

The invention relates to a method for producing a coil winding which consists of one or more coil layers. If a coil winding has a plurality of coil layers, the individual coil layers have different numbers of turns, which mainly decrease from the inside to the outside. In order to guarantee identical coil layer heights, the cross-profile of the conductors or the conductor bundles is adapted by deforming the same. The aim of the invention is to make sure that the individual turns of the coil layers are wound neither at too high a pressure nor to loosely. For this purpose, the conductors or conductor bundles are deformed by means of a deformation device in a single process step at the same time as the deformed conductors or conductor bundles are insulated and the conductors and conductor bundles are wound. The height of the already wound part of the coil winding is continuously compared as the actual value with the theoretical value for the already wound part, a theoretical lead for the part of the coil layer to be wound is determined and the deformation device is adjusted in such a manner that the final axial length or height of the coil layer corresponds to a desired value or to the theoretical value. The invention also relates to a corresponding winding device.
