A aluminum thin-walled cylinder was used to replace the cable to finish the actual setting process of terminal. The interface pressure between the 110 kV prefabricated cable terminal and the stress cone was measured by the electrical measurement method and elastic mechanics theory. By finite element simulation analysis and comparing the calculating result and test result, a reasonable finite element simulation analysis model was established and the terminal setting process was simulated. Several analysis models with different interference were established to study the influence of interference, silicone rubber material parameter, and spring compression on the interface pressure. The results show that the maximum interface pressure is located in the middle of the maximum radius of stress cone. The interface pressure is proportional to the spring compression before the spring compressing to 90 mm, and the interface pressure changes little during the process of the spring compressing from 90 mm to 85 mm. The interfacial pressure is affected by the interference and the cross-sectional area of cable, and it is greatly affected by the elastic modulus of stress cone, and less affected by the elastic modulus of cross-linked polyethylene (XLPE) insulation.
