An electrical conductor carries a rated current in a high-current bushing of a transformer. The electrical conductor includes a conductor piece which extends along an axis and has a cylindrical envelope surface, a first electrical connection, and a second electrical connection. The first electrical connection has two contact surfaces which are aligned parallel to one another. Electrical losses of the electrical conductor are kept low, with a compact design. This is achieved, in part, because the second electrical connection is connected without a joint to the conductor piece, and the first electrical connection is hollow and, at right angles to the axis, has an oval profile with two longitudinal faces which form the two contact surfaces. In addition, a hollow electrical conductor section is arranged between the first electrical connection and the conductor piece, connects the first electrical connection to the conductor piece, and forms a smooth transition from the two contact surfaces of the first electrical connection to the envelope surface of the conductor piece.
