Abstract

The invention relates to a composite graphene optical fiber cable and a preparation method thereof. The composite graphene optical fiber cable comprises a silica fiber, a silica fiber cladding layer, a copper foil graphene film layer and a protection insulation layer. The preparation method is characterized by comprising the following steps of depositing and growing a layer of graphene thin film on a copper foil by a chemical vapor deposition (CVD) method to form the copper foil graphene film layer; coating a copper foil side of the copper foil graphene film layer with an adhesive layer; wrapping an outer layer of a fiber core of the silica fiber with the silica fiber cladding layer; winding the copper foil for growing the graphene thin film at the outer layer of the silica fiber to form a graphene optical fiber conductor; and coating the outer side of the graphene optical fiber conductor with the insulation protection layer to form the graphene optical fiber cable. The graphene has high conductivity, the electronic mobility of the graphene is more than 100 times of that of copper, a few electrons pass through the copper film layer, signal shielding is exerted on the optical fiber core, and the stability and low attenuation property of an optical signal are ensured; and the internal silica fiber is an optical signal transmission medium, the optical information signal is transmitted through the silica fiber, and the synchronous transmission of a power signal and the optical signal in the same graphene optical fiber cable is achieved.

Description

technical field [0001] The invention relates to the field of electric power transmission, and specifically relates to a power optical cable capable of simultaneously transmitting electric power and transmitting signals, that is, a composite graphene optical fiber cable and a preparation method thereof. Background technique [0002] Optical fiber cable, also known as power optical cable, refers to placing optical fiber in the ground wire of overhead high-voltage transmission line to form an optical fiber communication network on the transmission line. This structure has dual functions of cable and communication, and is generally called OPGW optical cable. There is also an optical cable in which the optical fiber unit is combined in the wire in the traditional phase line structure, which makes full use of the line resources of the power system itself, especially the power distribution network system, and avoids problems in frequency resources, routing coordination, electromagne...
