A large number of GIS basin insulators have been used in UHV AC transmission projects, of which the performance is directly related to the safety and reliability of power system. Reasonable insulation structure can improve the electrical properties of GIS basin insulators. In this paper, the multi-objective algorithm has been used to optimize the insulation structure of GIS basin insulator. The evaluation function of multi-objective function is constructed by combining the judgment matrix approach with the linear weighting, and then transformed into single-objective optimization problem. The optimization has achieved good results. The electric field intensity on the typical positions of GIS basin insulator could satisfy the criteria values. The maximum electric field strength on the interface between the center conductor and basin body decreases from 13280 V/mm to 10271V/mm, reduced by 22.65%.
