Pre-twisted wire material and structure optimization design based on electrical performance requirements

The work of the railway overpass armor rod preformed is also related to the electrical performance of the entire railway contact network system. In some cases, preformed armour rod not only needs to achieve mechanical connection, but also needs to ensure the good electrical connection. For example, in some parts where current needs to be conducted, armor rods it is necessary to allow the current to pass smoothly while ensuring the stability of the mechanical connection. This requires that the material and structural design of armor rods for acsr meet the requirements of electrical performance.
