NOVELTY - An electromagnetic shielding tube, comprising a polymer resin protective layer, a metal layer, a resin layer, wherein the electromagnetic shielding tube further comprises a nano graphene electromagnetic shielding layer; the electromagnetic shielding pipe is provided with a polymer resin protective layer, a metal layer, a nano graphene electromagnetic shielding layer and a resin layer in turn from outside to inside. The device improves the rigidity of the pipe ring, at the same time, the electromagnetic shielding effect is better. Specifically, the nano graphene coating is made into electromagnetic shielding layer; the preparation method is simple and can improve the application performance of the existing submarine cable. The electromagnetic shielding layer is introduced in the way of laying, which can reduce the gap between the pipes and improve the electromagnetic shielding effect. The nano graphene coating can impart high impact resistance to the polymer pipe, corrosion resistance, which greatly reduces the cost and has no influence to the environment.
