Characterization Parameters and Control Criteria for Conductor Tension Stringing Defects

The accumulation of conductor torque during tension stringing construction is the main factor causing stringing defects (such as scattered strands, lantern, etc.), but conductor torque cannot be directly measured during tension stringing construction. This article converts torque detection into measuring the axial rotation of the conductor, proposes a detection scheme for the rotation count of the conductor during stringing, designs and develops wireless torque measurement sensors, conducts tension stringing torsion count measurement experiments. Characterization parameters and indicators of conductor stringing defects are extracted, and these indicators are compared and verified with simulation results. The results indicate that the characterization parameters for detecting conductor stringing defects are determined by the number of turns per hundred meters of conductor stringing between the tension machine output and the first base tower.
