Abstract

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 ( 3 b, 3 c ) protrudes beyond the cable ( 2 ). The unit of cable ( 2 ) and cryostat ( 3 ) is transported to the placement location. The ends ( 3 b, 3 c ) 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.

First claim

The invention claimed is:

1. A method of arranging and connecting a superconductive cable system to cooling units of an energy supply of a municipal network, said method comprising:
mounting at least one superconductive cable in a tubular cryostat, the cryostat serving for guiding a cooling agent,
transporting said cryostat, equipped with the cable to a placement location; and
connecting both ends of both the cable and the cryostat to respective said cooling units of an energy supply of a municipal network,
wherein the cable is mounted in a cryostat, the cryostat protruding at both axial ends of said cryostat beyond the ends of said superconductive cable, and
wherein the ends of the cryostat, protruding beyond the ends of the superconductive cable, are shortened, after said cryostat and superconductive cable are at the placement location to a predetermined length.

2. The method according to claim 1 , wherein
said cryostat is composed of two metal pipes which are arranged concentrically at a distance from each other and, between the metal pipes, a vacuum insulation is arranged, and
at least at two axial positions between the two pipes vacuum locks are mounted between which a vacuum is generated.

3. The method according to claim 2 , wherein the vacuum locks are locked after the connection between the respective ends of the cryostat and the cooling units are evacuated.

4. The method according to claim 1 , wherein said cryostat is provided with a thermal insulation.
