A high temperature superconducting lead comprising a first end cap (12) electrically connected to a conductor at the warm end resistive stage of the system, a second end cap (14) which is electrically connected to a conductor at the cold or cryogenic end of the system, and a main body (16) which electrically connects the first end cap (12) to the second end cap (14), and essentially thermally insulates the first end cap (12) from the second end cap (14). The first end cap (12) and the second end cap (14) each include an inner core (48) and cylindrical body (36) defining an annulus (50). High temperature superconducting fibers (52) are encapsulated within respective inner core (48) and the outer cylindrical portion (46) of the main body with epoxy resin having a thermal expansion of the high temperature superconducting material. A magnetic shield made from a ferromagnetic material may be disposed around the main body (16) of the lead to prevent electromagnetic interference from externally generated magnetic fields. |
