A high field/high voltage unit comprising at least one electrical component () and a solid insulating material () in the form of a first and a second piece part () which form, in particular, hard foam half bodies and a method of manufacturing same is disclosed. The piece parts () each have an inner structure comprising a plurality of preformed cavities () in which electrical components () are fixed. After assembly, the piece parts () form a closed casing of the high field/high voltage unit so that no extra steel vessel is necessary. Conductive paths () for the interconnection of the components are integrated into the insulating material () using for example an insert technology. Since several functions can thus be integrated into the solid insulating material (), a simple solution for assembling and disassembling an oil/gas filled high field/high voltage unit like a high voltage generator for an X-ray tube is realized.

Electrical high field/high voltage unit and method of manufacturing same

A high-voltage transformer, for an X-ray apparatus includes a high-voltage winding (4) which consists of at least one coil (5) which is supported by an insulating member (6). Heat dissipation from the coil is improved in that the coil is wound so as to be self-supporting and have a stable shape without requiring the use of supporting members and/or intermediate insulating elements, a small part of its surface being connected to the insulating member so that the greatest part of its surface is situated a distance from the walls of the insulating member.
