Abstract
The cable connection for low-temperature cable in which a pair of cable ends are joined. Each cable comprises a plurality of generally coaxial ducts defining a central compartment traversed by the electrical conductor or a plurality of electrical conductors in a sheath of electrical insulation and a pair of evacuated (vacuum) compartments surrounding the central compartment. Between the two vacuum compartments there is provided a coolant-filled compartment. In the connector, the evacuated compartments of the two cable ends overlap axially and the connection is formed by rigid, preferably cylindrical, walls.
Claims10
A cable junction comprising a first cable end and a second cable end, each of said cable ends comprising a first duct defining a central compartment and an electrical conductor and traversed by a first coolant, a second duct around said first duct and defining therewith an inner vacuum compartment, a third duct surrounding said second duct and defining therewith another coolant-traversed compartment, and a fourth duct surrounding said third duct and defining therewith an outer vacuum compartment;
- the compartments of one of said cable ends being offset radially outwardly in relation to the compartments of the other of said cable ends, the vacuum compartments of said one cable end axially overlapping the corresponding vacuum compartments of said other cable end, rigid wall means separatng the overlapping vacuum compartments from each other and said rigid wall means forming part of a rigid connection of said ducts of said other cable end from the interior to the exterior.
