Abstract (en)
[origin: EP2250956A1] The system (1) has a casing inner tube (2) exhibiting a reduced cross section than a casing outer tube (3) so that the casing inner tube and the casing outer tube form a telescopic casing channel (6). A suction inner tube (4) is arranged in the casing channel, where a cable (5) i.e. spiral cable, is guided within the casing channel. A suction outer tube (7) and the suction inner tube form a closed suction channel (8) within the casing channel, where length of the suction channel corresponds to length of the casing channel. Semi-shell elements (14, 15) are designed in a telescopic manner.
