Abstract: In this experiment, we carried out the measurement of conductor icing weight based on tension sensor and wind loading stress measurement based on three-dimensional force balance in cold mountainous area, and explored the feasibility of observation device and test method.Through the analysis of the test results represented by Dajingliangzi Station in Xichang, the following conclusions are drawn.The results show that the test methods of ice weight observation based on tension sensor and wind load stress observation based on three-dimensional force balance are feasible, and the observation data are true and effective, which have the ability of continuous observation of wire icing.The wind resistance coefficient calculated from the observation data of wind speed and wire force, which is equivalent to its typical value.The field test of conductor icing weight and wind loading stress in cold mountainous area can accumulate observation data for evaluation of conductor mechanical model, and it is of great significance to study the load basic characteristics and evolution mechanism of conductor icing and strong wind.
