Abstract
In this paper, Maxwell software is used to establish the electric field models of three different electric field control types of cable middle joints, and the electric field stress dispersion effects of non electric field stress control, stress tube parameter control and stress cone geometric control are simulated respectively. The simulation results show that the electric field stress evacuation effect of the cold shrinkable cable middle joint is better than that of the heat shrinkable cable middle joint, and is also much better than the free middle joint without stress control. The change of the electric field stress were also simulated after the change of the condition parameters, such as the the εγ and length of the heat shrinkable stress control tubes, the internal curvature radius and the installation displacement of the cold shrinkage stress cone.
