Development and test of 35kV/2kA high temperature superconducting cable termination

Abstract

HTS Cable termination as an important component of HTS Cable is to connect the HTS Cable and Outer terminal. The main components of HTS cable termination are current lead, electrical insulator, cryostat and Liquid Nitrogen. To development and test of HTS cable termination, the electrical field analysis, cryostat design and high voltage test technologies are needed. It is developed and tested of a cold dielectric HTS cable termination applying in distribution network. This paper reports two types of 35kV/2kA level HTS cable terminations, that is, bushing type termination and insulator type termination. The insulation design, two type termination structure and test results are shown.
