Abstract
In a feed-through unit of a conductor (2) through an opening in a conducting wall, the conductor together with shunt elements connected between the conductor and the wall--which shunt elements have a first and a second contact surface with a conducting coating--forms a rotationally symmetrical or mirror symmetrical configuration which completely or substantially closes the opening. In order to guarantee an even thermal stress on the individual shunt elements, the latter are so formed that the first contact surface and the second contact surface run parallel and the shunt element is located in each case essentially between the two contact surfaces. Several shunt elements can be arranged in shunt rows, whereby successive shunt elements are seriated either directly or separated by conducting intermediate layers. When a conductor designed as a strip conductor and cuboid shunt elements are used, shunt rows can also be connected in parallel and arranged directly adjacent to one another with intermediate layers extending transversely through the parallel shunt rows.
