Non-plastic Deformation Requirements In Pre-stranded Wire Installation Process

In the field of overhead line construction and hardware system design, there is an increasing discussion on the technical details of armor rod preformed construction. The industry's understanding that "preformed armour rod does not require plastic deformation during installation" reflects the attention paid to material condition and installation methods during the construction process. The armor rods structure is essentially made of multiple metal wires wound in a predetermined spiral shape. This structure allows it to generate gripping force using the principle of geometric interlocking when installing wires on site, avoiding mechanical deformation or plastic processing of the wire body during installation. This concept has been reflected in the application of patented technology.

Installation Process Requirements

For on-site construction teams, the installation steps of armor rods for acsr emphasize the mechanical compatibility of the operation process. According to some device patent descriptions, when winding armor rods transmission line onto the conductor or splice, no additional tools are needed to change the wire geometry; instead, fixation is achieved based on the elasticity of the spiral structure itself and the winding action. This method reduces the processing pressure on workers of high-strength materials and minimizes secondary impacts on the performance of armour rod.

On-site Quality Control

At the quality control level, the focus is on the construction personnel's control over the winding direction and contact surface of armour rod in transmission line. Because the armor rods conductor coils create a mechanical locking relationship with the conductor surface through their own structure during the winding process, the construction effect mainly depends on the standardization of operation and the consistency of winding in the absence of plastic deformation. This is significant for improving the repeatability of on-site installation and the neatness of the appearance.
