Abstract
The invention relates to a bushing-type transformer (1) comprising a conductive element (5) forming the primary conductor, supporting a flat contact surface (7) on one end thereof and a plug-in contact element (8) on the other end thereof, whereby the plug-in contact element (8) is embodied in a rotationally symmetrical manner and the rotational axis is arranged parallel to the flat contact surface (7). Said transformer also comprises a secondary winding (6) which surrounds the conductive piece (5) in an annular manner. The conductive element (5) extends in a linear manner and the plug-in contact element (8) is arranged on the surface area of the conductive piece (5).
