A high-voltage transformer and method of manufacturing are disclosed. The high-voltage transformer can include a transformer core having at least two core limbs, which are axially parallel and on which in each case a hollow-cylindrical coil having in each case at least one electrical winding is arranged. At least in partial regions of mutually facing surfaces of adjacently arranged coils, the respective surface regions of the coils can have a respective electrically isolating barrier structure, which can be integrated radially on an outside of the coil.

High-voltage transformer

A transformer winding and a dry-transformer are disclosed, which include a main transformer winding, and a supplementary transformer winding configured to be electrically connected in series with the main transformer winding. The supplementary transformer winding can include a first winding module, a second winding module, and a third winding module, each of the winding modules having at least a first, a second and a third winding segment, and wherein each of the winding segments has a tap. A changer is configured to be connected to the taps of the second winding module, and wherein the second winding module is configured to be electrically connected in series to at least one winding segment of the first winding module and the third winding module.
