Low resistance superconductor cable splice and splicing method

摘要

A low resistance splice for electrically connecting the ends of two superconducting cables and a method for making the splice. Two cables formed from superconducting material are positioned in close proximity, either overlapping or axially aligned and extending in opposite directions away from the splice. At least one strand of superconducting material is wrapped over both cables in a pressure relationship assuring good electrical contact between cable ends and strands. Solder is melted and applied to hold the strands against the cables. Where the cables overlap, solder may be used at the overlap interface to add mechanical strength. The strands may be in the form of a helical winding around overlapping cable ends or in the from of a braided tube surrounding and pressed against either overlapping or axially aligned cables. In the axial embodiment, the cables with the strand wrap may be pressed into a slot and the slot filled with solder to hold the cables and strands in position.
