We use preformed armour rods for ACSR conductor in transmission lines, the main reason is that it can avoid the risk of wire damage from the root cause and build a line of defense for the safe operation of the line. The transmission wires are exposed to the wild all year round. The dancing of the wires caused by high winds and the increased load caused by icing will cause repeated friction between the wires and the metal fittings, causing the outer aluminum strands to wear out or even break. Branches, iron wires, and accidental bumps in construction that fall during bird nesting can also directly damage the structural integrity of the wire. Traditional protection methods, such as tape winding, have the disadvantage of poor adhesion and easy aging and shedding. The repair pipe can only cover local damage and cannot form continuous protection. Once the protection fails, the light will lead to an increase in line operation and maintenance costs, and the heavy will cause disconnection and power outages, causing millions of economic losses. And our preformed armour rods for ACSR conductor adopts a high-strength aluminum alloy preformed forming process, which can be fitted with the same curvature as the wire, and the friction and impact forces can be evenly dispersed to the entire surface of the guard line to avoid local stress concentration of the wire.
The secondary reason for using preformed armour rods for ACSR conductor in transmission lines is to strengthen the mechanical properties of the wires, extend the life of the wires, and reduce long-term operation and maintenance costs. 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. If they are under extreme conditions, the wires can easily be broken or disconnected due to stress concentration. Traditional reinforcement schemes, such as hydraulic repair pipes, can only repair the damaged parts and cannot prevent potential fatigue failure. Our preformed armour rods for ACSR conductor can disperse the tension of the wire to each twisted wire through a collaborative force design, not only can the mechanical strength be restored to more than 90% of the original design value when the wire is slightly damaged, but it can also be embedded in the new line in advance, through active protection to delay the fatigue and aging of the wire. The dual value of repairing and preventing lines is a core advantage that traditional products cannot overcome.
In addition, the choice of preformed armour rods for ACSR conductor is also to simplify the construction process, improve engineering efficiency, and adapt to the complex needs of multinational projects. Traditional wire protection and reinforcement schemes rely on large-scale hydraulic equipment. Not only is the transportation cost of the equipment high, but it also requires professional personnel to operate. The installation of a single group takes a long time, which will seriously slow down the construction progress. Our preformed armour rods for ACSR conductor adopts a modular design, without the use of special tools, the construction efficiency can be increased by more than 4 times compared with traditional solutions, and labor and equipment investment can be reduced. More importantly, as a supplier who has been deeply engaged in the field of power fittings for many years, we understand the high quality requirements of B-side buyers. Our products have passed a number of international certifications and can provide customized designs according to your project needs. We look forward to establishing in-depth cooperation with you.
