Characterization of bearing capacity of 10 kV distribution line under ice and wind loads

Abstract It is challenging to test the displacement of distribution lines under ice-cover conditions because of the complexities involved in the measurement and environment setup and the high associated costs. In this paper, the wire type and span distance of the distribution line are determined based on the line’s operating parameters, and the suspended catenary’s initial shape is calculated. A finite element analysis model of the distribution line under ice-loading conditions is established by using simulation software. The model simulates the effects of self-weight load, ice load, wind load, and other typical forces on the bearing capacity of the distribution line. The results demonstrate that the ice thickness of ice cover, span distance, and wire type significantly influence the bearing capacity of a 10 kV distribution line. This study on the bearing capacity characteristics of the 10 kV distribution line under ice and wind load conditions provides valuable insights for the prevention of line failures and damages. Moreover, it offers a reference for the selection of distribution lines in different geographical locations and various engineering applications.
