Review and Outlook of HTS Cable Research

High-Temperature Superconducting (HTS) cable has the merits of high capacity, low line loss, narrow corridor, and environmental friendly, which has bright prospects for current tendency of accelerating development of renewable energy, shortage of available land, and awakening of environmental awareness. In the past decades, HTS cable technology made remarkable progress. Based on the past and current situation, the paper introduces the HTS materials for cable and presents the structures, classification, heat losses, and cryogenic method of HTS cable. Overview of HTS cable research in typical country is stated and representative HTS cable projects are listed. In the end, application outlook and development tendency of HTS cable in the future are made.
