Abstract
In this presentation we discuss the design of a termination for a
high temperature superconducting power cable with the following
design: A cable conductor consisting of superconducting tapes
wound onto a tight flexible tube (former) is placed inside a
thermally insulating jacet (cryostat). This assembly is
electrically insulated with an extruded polymer dielectric kept at
room temperature. Cooling is provided by a flow of liquid nitrogen
inside the former. The purpose of the termination is to connect
the superconducting cable conductor at cryogenic temperature to
the existing power grid at room temperature and to connect an
external cooling machine at ground potential to the cable. Some of
the aspects that have to be considered include the thermal
insulation of the termination, the transition from superconducting
tapes to a normal conductor, the current lead carrying current
between high and low temperatures, the transfer of liquid nitrogen
over a high voltage drop and that of providing a well defined
atmosphere inside the termination and around the cable conductor.
Designs based on calculations and experiments will be presented.
The solutions are optimized with respect to a low heat in-leak.
