The biggest advantage of using preformed armour rods for ACSR conductor is that it builds a comprehensive and long-lasting safety protection for transmission wires, eliminating the risk of outages caused by wire damage from the source. Transmission lines are exposed to the wild environment all year round, and they need to withstand mechanical friction caused by high winds, icing, and dancing, as well as local damage caused by bird nesting and foreign body impact. These problems cause the outer aluminum strands of the wire to break, and the heavier ones cause disconnection accidents, causing huge economic losses. The coverage of traditional protection methods is limited, and the protection effect is also very general. However, our preformed armour rods for ACSR conductor adopts a preformed design of high-strength aluminum alloy twisted wire, which can form a seamless wrapping structure with the wire, which can disperse the impact force of friction damage and foreign body impact to the entire protective line surface to prevent local stress concentration of the wire. After third-party testing, under the same operating conditions, the installation of the wires of our products has reduced the wear rate of the outer aluminum strands by more than 92%, and our products have passed the salt spray test and the high and low temperature cycle test, and can still maintain stable protection performance for several years in extreme environments such as coastal salt spray areas and desert high temperature areas, completely solving the pain points of short protection cycles and poor adaptability of traditional products.
And preformed armour rods for ACSR conductor can significantly improve the mechanical properties of the wire, extend the service life of the line, and provide long-term reliable structural support for the project. This is its main advantage that distinguishes it from ordinary protective products. In the span section and large-range section of high-voltage and ultra-high-voltage transmission lines, the wires need to withstand greater tension and fatigue loads, especially under extreme meteorological conditions, the wires are prone to strand breaks and disconnections due to stress concentration. Our preformed armour rods for ACSR conductor can evenly distribute the tension of the wire to each twisted wire through the collaborative force design, which can not only restore the mechanical strength to more than 90% of the original design value when the wire is slightly damaged, but also prevent fatigue damage in advance in the new line. This dual function of protection and reinforcement has made it a standard configuration for routes across complex terrain such as rivers and mountains, completely getting rid of the limitations that traditional products can only protect and cannot be reinforced.
At the level of engineering efficiency and cost control, the simplification of construction and the reduction of operation and maintenance costs brought about by preformed armour rods for ACSR conductor are the core needs of B-side buyers. Traditional wire reinforcement schemes, such as hydraulic repair pipes, need to rely on professionals to operate large-scale hydraulic equipment. Not only is the transportation cost of the equipment high, but it also faces operational problems in complex operating scenarios such as high altitude and mountainous areas. The installation of a single group takes up to 1 to 2 hours, which seriously affects the construction progress. And our preformed armour rods for ACSR conductor adopts a modular design, which does not require special tools. Two workers can complete a set of installations in 15 minutes. The construction efficiency is significantly improved compared to the traditional scheme, and labor and equipment investment are greatly reduced.
For buyers who pursue a balance between engineering quality and cost, choosing preformed armour rods for ACSR conductor is actually choosing a long-term solution that is safe and secure, improves efficiency, and optimizes cost!
