Abstract

An end closure for a superconductive electric cable which has at least one superconductive conductor which is surrounded by a tubular cryostat serving for conducting a cooling agent, which at its end is surrounded by a housing. The housing (G) has two walls (7, 8) which are separated from each other by an intermediate space (9) and having insulating material, wherein a thermal insulation containing gas is placed in the intermediate space. The pressure in the intermediate space (9) of the housing (G) is adjusted to a value of between 10−9 mbar and 1000 mbar and, connected to the intermediate space (9) are a pressure measuring device (12) and a vacuum pump (11) which serve for adjusting the pressure prevailing in the intermediate space (9) of the housing (G).
