Abstract:
The invention relates to a drill rod having at least two rod elements, which are connected to each other in a rotationally fixed and detachable manner, wherein the rod elements each have an inner pipe and an outer pipe, between which a ring-shaped receiving space is formed, the rod elements each have an energy and/or data line, which extends along a longitudinal axis of the drill rod, and the energy and/or data lines of the rod elements are each connected to an induction coil, wherein the induction coils can be coupled to each other inductively for energy and/or data transmission along the drill rod. A first rod element has an inner induction coil located at an outer circumference of its inner pipe and a second rod element has an outer induction coil located at an inner circumference of its outer pipe.
