NOVELTY - The utility model claims a graphite low-noise cable, comprising an inner conductor, an inner shielding layer, an insulating layer, an outer shielding layer, an external conductor and an external sheath layer, the shielding layer is extruded outside the inner conductor, the insulating layer is extruded outside the inner shielding layer, the outer shielding layer is wrapped outside the insulating layer; the outer side of the outer shielding layer is provided with an outer conductor, and the outer side of the outer conductor is extruded with an outer sheath layer. The utility model adopts the graphene composite polymer material as the inner conductor of the cable and the shielding layer and an insulating layer on the insulating layer and the shielding layer material between the outer conductor and reduces the disturbing noise from the cable in the physical reasons such as material, structure generation, the noise value is far less than 1mV, good noise reduction effect.
