▎ 摘　　要

NOVELTY - The cable has a power cable provided with a conductor assembly (100), a shielding layer (200) and an armor layer covered in sequence from a center of a power cable to a direction of an outer wall. The armor layer is a carbon fiber graphene composite armor layer. The shielding layer is an aluminum wire shielding layer. The conductor assembly includes a water-blocking conductor, a conductor shielding layer, an insulating layer and an insulating shielding layer which are coated sequentially. The water-blocking conductor includes multiple guide wire layers coated in sequence, and first water-blocking layer is arranged between two adjacent guide wire layers. USE - Power cable for transmitting and distributing electric energy in urban underground power grid, power station, industrial and mining enterprise internal power supply and river sea underwater power transmission line. ADVANTAGE - The power cable solves the technical problem that when the power cable is vertically laid, it is easy to generate large amount of electromagnetic wave in the process of damage caused by pulling and pulling caused by self-weight, and easy to interfere with the normal work of the oil gas collecting instrument. The shielding layer and the armored layer can play the role of electromagnetic shielding at the same time, and the shielding effect is improved. The carbon fiber graphene composite armored layer has high strength, the needed pulling force is larger, and density of the carbon fiber graphene composite armored layer is small, it reduces the weight of the cable and reduces the influence of the gravity when the cable is laid. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the power cable for transmitting and distributing electric energy in e.g. urban underground power grid. 100Conductor assembly 200Shielding layer 300Armour layer 400Second water blocking layer 600Fourth water blocking layer 700Outer sheath
