Abstract

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.
