The study on evaluation model for prefabricated HV stress cone of cable terminations weakness based on finite element

Abstract

The accurate model of the pre-fabricated HV stress cone of cable termination is set up. Further more, any of the weaknesses are also be consider to the model, such as the interface of the stress cone and the cable, the distortion of the cable termination by the torsion outside, and so on. In order to simulate the electric field of the pre-fabricated HV stress cone of cable termination, the finite element analysis method is used. And the results of the analysis are also illustrated. As a conclusion, the design rules are also expatriated
