NOVELTY - This new type utility claims one with a graphite conductive layer of high-voltage cable to solve the technology problem to be solved is high voltage cable provide a one can accurately detect non-metal jacket cable machinery seal property, safety and reliability of a conductive layer of graphene. In order to solve said technology problem, this utility new type using following technology solution is as follows: one with a graphene conductive coating of high voltage cable, include conductor, an outer conductor concentric is covered with a conductor shielding layer, insulation layer, insulation shielding layer, buffering layer, metal sheath layer, anticorrosive layer, an outer non-metallic sheath layer, a non-metal outer sheath layer is further set with graphene conductive coating. This utility new type with the existing technology, the current high pressure cross-linked cable outer sheath layer outside using of non-metal conductive graphite coating is changed into graphene conductive coating can be safety and reliability of cable operation of detection accuracy and greatly improves cable non-metal jacket machinery seal property.
