    Abstract: This paper aims to research the high resistance value of the fusion tube electrode loop of the medium voltage ring main unit problem. It analyzed the influencing factors of the high loop resistance value from the aspects of part design, machining process, assemblage,and testing. In addition, it proposed the improvement plans from different perspectives, such as the size and appearance of the screw thread,anti-loosening performance of the screw thread. Moreover, this article provided references and guidance for the fusion tube electrode assemblage and the loop resistance test. The result shows that this research result help to improve the reliability and accuracy of the measurement result of the fusion tube electrode loop resistance.
    Key words: ring main unit; fusion tube electrode; loop resistance; influencing factors
