Patent ID: 8306591

Claim:
A superconducting cable terminal connection device which connects a terminal of a superconducting cable for power transmission to an external power system, comprising: an electric field relaxation shield disposed inside an insulation housing; a horizontal conductor fixed to an end portion of a core of the superconducting cable drawn into the electric field relaxation shield; an insulator which coats an outer periphery of the horizontal conductor; a vertical conductor which is drawn into the electric field relaxation shield and has a through-hole through which the horizontal conductor and the insulator pass so as to be slidable in a lengthwise direction; and a flexible electrical conduction member which electrically connects an end portion of the horizontal conductor to the vertical conductor, wherein an outer peripheral portion of a lower portion of the insulator of the horizontal conductor is put on a bottom of an inner periphery of the through-hole so as to be slidable, so that a weight of the horizontal conductor is supported and sliding movement of the horizontal conductor in the lengthwise direction is allowed by the through-hole of the vertical conductor.
