NOVELTY - The utility model claims an environment-friendly graphene layer railway through ground wire and wire breaking alarming system, ground comprises alarming wire, stranded conductor layer and a protection layer; the alarming line is composed of a conductor and an insulating broken line alarming line core and the stranded conductor layer is the non-circular single wire concentric twisted; the protecting layer is a sealed metal tube, the metal tube is coated with a graphene coating layer. The utility model adopts wire conductor stranded structure, and only wires can form a self-supporting structure can better protect the communication alarming wire core, avoid damage, but also makes the structure more compact and smaller outer diameter, save metal pipe material, a graphene coating layer coated outside the metal pipe, which can greatly improve the corrosion resistance of the metal pipe through earth wire, which greatly improves the service life.
