Abstract
A pipeline with threaded pipes and a sleeve connecting the pipes which is hung in a drill hole for transporting a liquid and/or gaseous medium. An electrically driven pump or compressor is arranged at the start of the pipeline in the region of the base of the drill hole and the electric motor is supplied with electric power via a cable hung in the drill hole. In order to allow for large cable cross sections for the electric drive of a turbopump or a turbocompressor and to prevent impermissible loading of the cable, each sleeve of the pipeline has at least one groove extending in the longitudinal direction at its outer casing, the cable being guided in this groove.
