Differences In The Structures Of Different Types Of Railway Cross-line Pre-twisted Wires

Different types of railway overpasses armour rod in transmission line have some differences in structure and purpose. For example, the internal structure and size of armor rods conductor, which is used to connect contact wires of different specifications, will be specially designed according to the thickness and material of the contact wire. For thicker contact wires, the inner diameter of armor rod preformed will be larger, and the number and diameter of the twisted steel wires may also be adjusted accordingly to ensure that sufficient holding force and friction can be provided.
