Abstract

A current lead (1) for connecting a superconducting load system (5), in particular, a magnet coil, to a current feed point (3a) that is at a higher temperature than the load system (5) comprises a flat, elongated carrier (6) and a plurality of mechanical and electrical parallel high-temperature superconductors (HTSC) (10), wherein the HTSCs (10) are disposed side by side on the carrier (6). The carrier (6) is made of stainless steel, and a plurality of HTSCs (10) are each disposed side by side on two opposite carrier (6) sides of the carrier. The carrier (6) is constituted in the shape of a plate with cut-outs (15; 15a-15d). The current lead has a high current capacity and low thermal conductivity and provides improved emergency conduction properties in case of failure of the superconductivity in the HTSC.
