ABSTRACT:
A conductor splice and splice support structure and method of assembly for use with cable-in-conduit superconductor cable of the type having a plurality of spaced sub-cables each including stabilizer and superconductor strands in an annular tube. Two transition ramp members, each having a cross section varying from a first end conforming to the cable configuration to a second end having an enlarged, oval, configuration have a plurality of surface grooves each sized to hold one sub-cable. Between the two transition ramp members is provided a main support member having grooves aligned with the transition members grooves. The main support member grooves are sized to hold two overlapping sub-cables. Preferably, a braid of superconductor material is placed around the overlapping sub-cable ends. The space within the grooves surrounding the sub-cables is preferably filled with solder. A housing is preferably formed around the splice, with a connection through which a coolant, such as liquid helium, can be admitted to the splice and cables.
