How Does Pre-twisted Wire Work?

When armor rod preformed is working, the elasticity and friction of preformed armour rod itself are used to achieve a stable connection. When the railway train is running, the contact network will be affected by various external forces such as vibration and wind. The elasticity of armor rods can buffer the impact of these external forces on the connection parts and prevent the connection from loosening. At the same time, the friction generated between armor rods for acsr and the surface of the wire can effectively prevent relative sliding between armor rods transmission line and the wire, thereby ensuring the reliability of the armour rod connection.
