Superconducting cable main insulation design occupies very important position in the design of the superconducting cable. This paper introduced the cold insulation HTS cable main insulation design methods and the test method of the insulation performance. For the superconducting cable withstand voltage, design field strength and determination of the insulation thickness and superconducting cable main insulation performance test were all analysed in details. The influence of quench - induced partial discharge characteristics on the main insulation design was introduced. The design method and performance test method introduced by this paper provide some reference for the superconducting cable main insulation and insulation performance testing.
