本文以25kV冷縮式電纜終端接頭元件為主要架構，使用有限元素分析法模擬(1)電應力緩解材料的厚度改變(2)電應力緩解材料的相對介電係數改變(3)不同的應力錐幾何尺寸(4)埋置接地電極時的電場與電位分布狀況。並依模擬結果提出最佳的電應力改善方式。所有模擬均使用COMSOL Multiphysics 軟體完成，COMSOL Multiphysics為一使用有限元素法的模擬軟體。
模擬結果顯示，電應力緩解材料厚度增加時，有助於降低電纜屏蔽末端之電場強度,材料的相對介電係數愈高，電場亦會隨之降低。應力錐長度增長或使用埋置接地電極方式均可降低電纜屏蔽末端之電場,但需注意埋置接地電極末端電場仍有集中現象以及電應力緩解材料本身的損失問題。

This thesis with cold-shrink 25kV cable terminal connector components as the main structure, used finite element analysis method to simulate the following situations (1) with different thickness of stress relief material (2) with different relative permittivity of stress relief material, (3) different geometries of the stress cone , (4) of a grounding embedded electrode to monitor effects of electrical stress grading. And in accordance with simulation results to take the best way to improve the electrical stress. All simulations completed by COMSOL Multiphysics , COMSOL Multiphysics is a finite element method simulation software.
Simulation results show that electrical stress relief material thickness increases will reduce the electric field strength on the end of cable shielding. The higher the relative permittivity, the lower the electric field will be . Increasing the length of the stress cone or using embedded electrode also can reduce the electric field on the end of cable shielding, but we should pay more attention to the end of the embedded grounding electrode which the electric field is still focused and considered the dielectric losses of the electrical stress relief material .
