Abstract:
A terminal apparatus for use with insulated power cable comprising a rigid housing having an elongated bore for receiving a terminal end portion of the cable, and an elastomeric sealing means at one end of the bore. The sealing means extends into the bore from said one end towards the opposite end for a distance substantially less than the length of the bore, and the remaining portion of the bore is filled with dielectric insulating fluid and a load bearing insulation system that maintains the sealing means in air-free sealing engagement between the bore and the cable regardless of service temperature variations.
Abstract:
A transition conductor comprising a tubular envelope has one end dipped in a cryogenic fluid and the upper section connected to an external current source with cryogenic fluid raised in the tubular envelope during current application to the load emersed within the cryogenic fluid.
Abstract:
An electrical superconductor comprises a hollow prismatic member consisting of a cylindrical tube covered with an extra layer of the slightly resistive material to form the external shape, and containing superconductor elements, and a lining of mechanically strong material, fixed onto the prismatic member.
