The arrangement has three components (4-6) comprising inner, center and outer phase conductors (7-9), respectively, The components comprise superconductive material made of rare earth metals such as yttrium-barium-copper oxide or bismuth-strontium-calcium-copper oxide. The components are arranged in a cryostat (KR) that comprises two metallic tubes (1, 2). A vacuum insulation (3) is fitted between the two metallic tubes, and the cryostat surrounds a free space (FR). The inner phase conductor is connected to the centre phase conductor that is connected to the outer phase conductor.
