Abstract

The invention relates to a power transmission line energy-saving capacity-increasing wire and a preparation method thereof, and belongs to the technical field of wires. The power transmission line energy-saving capacity-increasing wire comprises a carbon fiber composite core and an aluminum wire wound outside the carbon fiber composite core, the carbon fiber composite core is formed by twisting anisolation layer outside a carbon fiber core; the carbon fiber core is formed by twisting a plurality of strands of fine carbon fiber cores; the fine carbon fiber core is prepared from the following raw materials in parts by weight: 10 to 20 parts of carbon fiber, 50 to 70 parts of epoxy resin, 5 to 12 parts of polydimethylsiloxane, 1 to 8 parts of dimethyldichlorosilane, 1 to 5 parts of toluene diisocyanate, 0.1 to 5 parts of nano zinc oxide, 0.01 to 1.2 parts of polydopamine, 0.1 to 3.5 parts of curing agent and 30 to 50 parts of solvent. The energy-saving capacity-increasing wire of the power transmission line is used for reducing the direct-current resistance of the wire and increasing the current-carrying capacity of the wire.

Description

technical field [0001] The invention belongs to the technical field of conductors, and in particular relates to energy-saving and capacity-increasing conductors for power transmission lines and a preparation method thereof. Background technique [0002] The transmission wire is the main component of the overhead line. It is responsible for the transmission of electric energy from the power source to the power load center. It occupies an extremely important position in the transmission line. The overhead transmission wire generally uses steel-cored aluminum stranded wire. With the continuous acceleration of my country's economic development, the demand for electricity has further increased, and the traditional high-voltage transmission lines have been unable to meet the large capacity required for economic development at this stage due to years of operation, regardless of the amount of transmission or transmission distance. In order to meet the needs of transmission lines, it ...
