The interface pressure between cable and cable joint is of essential importance to ensure the electrical transmission safety. As there is no accurate formula to derive the exact interface pressure and the measurement of the interface pressure is quite complicated or may exist errors that cannot be ignored, it is difficult to design a cable joint that can meet all kinds of requirements. In this paper, series of finite element models are established by Ansys. They are based on a 110kV crosslinked polyethylene (XLPE) cable with cross-section area of 1600 mm2which is connected by its cable joint made of silicon rubber. The distribution of the interface pressure value along axis is studied. The relationship between the Young’s Modulus of the material of the cable joint is also analysed according to the models. Facts prove that the value the of interface pressure is changed along axis, and it is bigger in the middle of the cable joint. The interface pressure is directly proportional to the value of the cable joint’s Young’s Modulus. Using finite element method is of instructive significance and can save money and energy in the design of a cable joint.
