NOVELTY - The utility model claims a nano graphene medium voltage power cable, comprising a conductor, an inner shielding layer, an insulating layer, an external shielding layer, a copper belt shielding layer, a wrapping layer and outer sheath layer; the outer wall of the conductor is orderly covered with nanographene layer from inside to outside, an inner shielding layer, an insulating layer and an outer shielding layer, to form a group of insulating wire core, insulating wire core winding copper strip shielding layer form shielding wire core; the outer side of the three groups of shielded wire core covered with wrapping, wrapping outer side is covered with an outer sheath layer. The utility model uses the cable of skin effect, outside of the cable conductor by electrostatic coating nano graphene, adopting dry cross-linked technology, improves the carrying capacity of the cable, reduces the generation rate of water tree and improves the product quality.
