A rod section having an electrical conductor which is arranged such that it is centered at the end and has an insulating sleeve and is fixed in the rod section such that when the rod section is joined to a further rod section having a fixed conductor, both conductors are joined together in a forcibly guided manner and the join is sealed by the sleeve in a forcibly guided manner.

Rod section and rod section system

An earth boring apparatus includes a drill rod, a source for a drill fluid, and a voltage source. The drill rod has a hollow rod casing provided for throughflow of the drill fluid, and a conductor located within the rod casing, with the voltage source being connected with the conductor and the rod casing. The voltage source is so connected as to prevent the electric conductor to act as anode in the event the drill fluid establishes an electrically conductive connection between the rod casing and the conductor.
