Study on Stress Characteristics of Dry-Type Cable Termination Bending Operation

Abstract

For the present stage of the project more practical application of 110kV Bo-shaped down lead cable arrangement, cable terminal different bending angle stress distribution was simulated based on finite element numerical simulation, and determine the impact of the bending angle on the uneven distribution of the terminal internal stress to provide reference for the determination of practical engineering cable terminal bending angle. The results showed that: Under the arrangement of 110kV Bo-shaped down lead cable, when the cable terminal bending angle of less than 5°, each layer of stress distribution is within the scope of its tensile strength, the safe and stable operation of the dry-type cable terminal can be ensured.
