| Abstract: | A new design method of single-line stress cone was presented in this paper. According to the insulation characteristics of PPLP and the body size and design voltage of superconducting cable, the paper gave the design data of added insulation thickness and axial length of stress cone. The thickness of added insulation and the axial length of stress cone were 3.5 mm and 38.5 mm respectively and the electric field numerical analysis of single-line stress cone was carried out. The results shows that the stress cone designed in this paper meets the operation requirements of 100 kV DC high temperature superconducting cable. |
