NOVELTY - The utility model claims a graphene shielding digital transmission cable, comprising a plurality of digital transmission twisted core wire covered by graphene shielding belt, and the digital transmission twisted core wire are symmetrically arranged; the outer side of the graphene shielding belt is coated with an outer sheath; the graphene shielding belt is a composite shielding belt, comprising a central layer from inside to outside, a first nickel-plated layer, a copper-plated layer, a second nickel-plated layer and a graphene layer. The utility model has simple and reasonable structure, has better electromagnetic shielding effect, reduces the cable cost and improves the EMI performance of the cable.
