Abstract
An electrical transmission line for conveying and limiting current by using a plurality of tubular portions made from a superconductive material. The tubular portions have a high critical temperature and are connected end-to-end by flexible, electrically conductive metal or alloy joints. A cryogenic fluid flows inside a first tube within the tubular portions. A vacuum is maintained inside a second tube around the tubular portions.
Claims19
An electrical transmission line for conveying and limiting current comprising:
- a plurality of tubular portions made from a superconductive material having a high critical temperature connected end-to-end by a plurality of flexible, electrically conductive metal or alloy joints, each of said tubular portions having an axial length;
- a first tube inside said tubular portions in which a cryogenic fluid flows, said first tube having electrical contact with each said tubular portion at fewer than all points along the axial length of each tubular portion;
- and
- a second tube disposed around said tubular portions, and in which a vacuum is maintained.
An electrical transmission line for conveying and limiting current comprising:
- a plurality of tubular portions made from a superconductive material having a high critical temperature connected end-to-end by a plurality of flexible, electrically conductive metal or alloy joints;
- a first tube inside said tubular portions in which a cryogenic fluid flows;
- a second tube disposed around said tubular portions in which a vacuum is maintained,
- wherein said flexible joints comprise a ring attached to a braid.
