There Is An Inherent Logic To Correctly Installing The Spiral Direction Of The Pre-twisted Wire.
In overhead line construction and maintenance, the installation of armour rod is not a random fixing process, but is closely related to its own structure. armour rod in transmission line is a cylindrical cavity structure pre-stretched from multiple metal wires in a specific spiral direction. This geometry determines not only its covering method but also the rationality of its installation direction.
When on-site workers wrap armor rods conductor along the conductor, moving armor rod preformed in the spiral direction allows the internal cavity to fit against the conductor surface. In this way, the stranded metal wires of the preformed armour rod can conform to the stranding direction of the conductor and interlock with the conductor to form a relatively stable mechanical contact. In practice, reverse operation often leads to localized warping or uneven tension distribution in the armor rods.
This spiral installation method is closely related to the product's manufacturing process. armor rods for acsr is stranded in a specific spiral direction during manufacturing, resulting in a continuous spiral structure. If the wrapping direction is opposite, armor rods transmission line will experience a deformation tendency opposing its own strand direction during loading, affecting its fit with the conductor.
