A method for constructing a superconductive cable system is proposed. Using this method, at least one superconductive cable (2) is mounted in a tubular cryostat (3) serving for guiding a cooling agent by means of which the cryostat (3) equipped with the cable (2) and wherein the cable (2) and the cryostat (3) are transported to the placement location and both ends are connected to units. The cable (2) is mounted in a cryostat (3) which at both axial ends (3b, 3c) protrudes beyond the cable (2). The unit of cable (2) and cryostat (3) is transported to the placement location. The ends (3b, 3c) protruding beyond the cable (2) are cut to a predetermined length. The superconductive cable (2) and the cryostat (3) are subsequently connected to the units.
