NOVELTY - The utility model relates to the technical field of signal transmission cable, specifically claims a graphene shielding type digital communication cable, comprising a signal transmission layer with a plurality of cable cores, a shielding layer and a sheath layer, the cable core comprises a bare copper conductor and a foaming fluorine plastic insulating sleeve sleeved with the bare copper conductor; the shielding layer comprises graphene shielding ring surrounding each cable core, an aluminium foil sleeve sleeved on the outer ring surface graphene the shielding ring, the aluminium foil sleeve is provided with a tinned drainage wire; The sheath layer is set on the outer ring surface of the aluminium foil sleeve. The cable is provided graphene a shielding ring for replacing the traditional shielding net wire of the aluminium foil and tinned copper wire woven shielding layer, reducing the copper wire drawing and shielding layer weaving process, saving the copper material; aluminium foil and tinned copper wire woven shielding layer is cancelled, reduces the outer diameter of the cable and reduces the sheath layer material dosage, reduces the cable cost, cable outer diameter is reduced to improve the flexibility, convenient for the cable through pipe; The shielding ring is made of material, graphene improves the shielding efficiency and anti-interference performance and ensures the integrity of the data.
