Conductor Holding Technology For Pre-twisted Wires And Aluminum Alloy Wires

Professional Structural Analysis of High-Performance Line Connections

In the design of high-voltage transmission and distribution lines, the structural and material selection of armor rod preformed plays a crucial role in the stable holding of the conductors. preformed armour rod uses aluminum alloy wire to hold the conductor, forming a tightly integrated force transmission structure to ensure that the conductor can maintain a stable position under external force. The mechanical properties and flexibility of the aluminum alloy wire directly affect the stress distribution of section armor rods.

Pre-twisted Wire Structure and Mechanical Distribution

Pre-twisted wire is composed of multiple strands of aluminum alloy wire twisted together. Each strand exhibits a slight bending state when bearing tensile force, conforming to the shape of the conductor surface.

• Twisting Angle: Different twisting angles affect the uniformity of force distribution. Smaller angles are beneficial for dispersing local pressure and reducing point stress concentration.

• Wire Diameter Specifications: The diameter of the aluminum alloy wire is matched with the number of strands to form a predetermined total cross-sectional area, supporting the conductor's own weight and external loads.

• Surface Treatment: The surface of the aluminum alloy wire undergoes specific processing to reduce changes in the coefficient of friction and improve the consistency of holding.

Stability Analysis of Conductor Holding

During load bearing, armor rods for acsr is held by aluminum alloy wire, exhibiting a linear stress distribution. The contact surface between the holding point and the aluminum alloy wire forms a continuous force chain, ensuring the conductor maintains its position under long-term use. Mechanical tests show that the stranded structure can maintain stability under various temperature and humidity environments.

By precisely designing the stranding method and aluminum alloy wire parameters of the armor rods transmission line, the gripping force can be scientifically distributed to avoid local loosening or displacement. The stress distribution on the conductor surface is uniform, maintaining the overall stability of the conductor while ensuring controllability during installation and maintenance.
