Method of electrically conductively connecting two superconductive cables

Method for electrically conductively connecting two superconductive cables which are each arranged concentrically relative to each other and are each surrounded by a dielectric, and have an electrically effective screen mounted above the outer dielectric by means of which the conductors and screens to be connected are initially freed of surrounding layers at the ends of the two cables and are subsequently electrically conductively connected to each other, said method comprising the steps of:

• the ends of the two cables are arranged next to each other and parallel to one another such that their free ends point in opposite directions and their conductors are located at least approximately on the same level;
• the ends of the two cables are secured relative to each other;
• two conductors of the two cables are always connected to each other electrically conductively through electrical contact elements;
• the screens of the two cables are electrically conductively connected through by means of separate contact elements;
• and
• the two cable ends treated in this manner are arranged in a housing of a cryostat for constructing a transmission length for electrical energy jointly in a housing of a cryostat which, during operation of the transmission length, a flowable cooling agent with electrically insulating properties flows through a housing of a cryostat.
