“…For HTS cables, the majority of the heat loads come from the terminal lead in the termination which transitions from room to cryogenic temperature and is made from a conventional conductor. Typical thermal load in the termination was estimated to be 350 W [13]. This leads to an added difficulty in removing the heat generated and maintaining the required cryogenic temperature for the HTS cable.…”

“…This leads to an added difficulty in removing the heat generated and maintaining the required cryogenic temperature for the HTS cable. There have been previous termination designs to help mitigate these problems, but these designs are not for large continuous thermal loads, and the complexity and size of terminations make them undesirable in an efficient and compact cryogenic system [13].…”

Large electric transportation systems such as electric aircraft and electric ships have been designed with multiple high temperature superconducting (HTS) power cables as part of superconducting power distribution network, and a good electric insulation for the power cables is a critical design requirement needed to be considered. This is because terminations in HTS cable represent a location of significant electrical and thermal stresses and needs to be addressed to reduce the substantial heat load that might be introduced into the cryogenic system. The use of a warm dielectric termination is seen as a potential solution to reduce the electrical standoffs required as part of the design and allow for a high-power dense termination design. A warm dielectric termination design using commercially off-the-shelf ceramic breaks as electrical breaks is explored and withstand and partial discharge measurements are performed to determine the viability of the design concept.
