Abstract
DC cable is the most important carrier of DC transmission, while the DC cable accessories is the weakest part of the whole cable system. When the load applied in the flexible DC cable system is different, each part of the joint insulating material temperature changes, which makes the conductivity changes. This paper has compared the calculation results of analytical method and finite element method by calculating DC cable. The results show the consistency of analytical method and finite element method. Through the research we fully grasp the law of the electric field distribution of joint insulation layer, provide the research foundation of flexible DC cable joint structure design and optimization, and also provide technical support for China's ±535kV and ±800kV UHVDC transmission project.
