The Effect Of Pre-stretched Wire On The Force Distribution In The Guy Wire And Insulator String

The armor rods is usually made by twisting together multiple metal wires. Its inner surface is treated to enhance its adhesion to the base conductor. This helical structure matches the stranded wire body, fitting tightly against the conductor during installation. This distributes the load along the strand axis, reducing single-point stress and creating a stable stress path within the overall structure.

In the configuration of tension insulator strings for transmission lines, armor rods for acsr is responsible for transmitting the load from the cable end to the insulator string. By configuring and controlling the length of the mechanical contact surface between armor rods transmission line and the conductor, the tension can be evenly guided to the next level of structure along the strand direction.

The helical stranding of armour rod not only transmits tension but also adjusts the local stress distribution when bending or changing stress conditions at the suspension point, which is crucial for maintaining the overall stress coordination of the insulator string.
