When The Conductor Is Under Tension, The Axial Tensile Force Of The Pre-twisted Wire Increases.

When the conductor bears external force, its linear tension causes the pre-twisted spiral coils to tend to align more closely. Due to the certain coefficient of friction between armor rods for acsr and the conductor, the spiral shape causes the tension along the axial direction to not be simply transmitted along the conductor, but to be converted into a component force along the spiral direction, thus forming a higher axial component tension force in armor rods transmission line itself. armour rod is in close contact with the conductor surface, causing part of the external load tension to be transferred to the armour rod in transmission line structure. Due to the amplification effect of the spiral geometry, this axial component force is significantly enhanced, manifested as the axial tension of armor rods conductor increasing with the increase of conductor tension.
