The invention provides a cable for charging piles for electric vehicles, a preparation method thereof, and a stranding device for a weak-current flexible wire core. A flexible wire core is formed by mixing and concentrically stranding aramid fibers and stainless steel wires, wherein the content of the aramid fibers is 80%-90%, and the pitch ratio is 5-10. The cable has good shielding performance and good bend resistance and heat resistance.
