Novel conductor corrosion-resistant direct-current cable

The invention discloses a novel conductor corrosion-resistant direct-current cable, which comprises a plurality of composite graphene conductors, an insulating layer, a water-blocking tape, an oxygen barrier layer and an outer sheath which are sequentially arranged from inside to outside, and is characterized in that each composite graphene conductor comprises a metal conductor and a graphene coating wrapping the outer surface of the metal conductor, and the metal conductor adopts a category 5 flexible conductor; the plurality of composite graphene conductors are stranded and then wrapped by the insulating layer, the insulating layer adopts an ethylene propylene rubber insulating layer or a crosslinked polyethylene insulating layer, the oxygen barrier layer adopts a low-smoke halogen-free oxygen barrier layer, the outer sheath adopts a low-smoke halogen-free flame-retardant polyolefin sheath, the metal conductor adopts a copper wire or an aluminum wire in a category 5 flexible conductor, and the water-blockin
