The invention relates to an electrical hollow conductor (1) in the shape of a tubular body (2) having a hollow interior (3), for continuously winding an electromagnetic coil, wherein the body (2) comprises an electrically conductive material, has an outside diameter and an inside diameter, and is coated with an electrically insulating layer (4) on an outer lateral surface of the body (2) and wherein the interior (3) is designed in such a way that the interior hydraulically or pneumatically connects a first opening of the body (2) and a second open end of the body (2). According to the invention, in order to specify an electrical hollow conductor (1) that can be used for small and medium electromagnetic machines, a ratio of the outside diameter to the inside diameter is in a range of 1.25:1 to 4:1. The invention further relates to a use of the electrical hollow conductor (1), a connecting piece for the electrical hollow conductor (1), and an electromagnetic machine that has the electrical hollow conductor (1). |
