Embodiment 1

[0024] Such as figure 1 The carbon fiber composite wire core shown includes an aluminum alloy cylinder 1 and carbon fibers 3 uniformly distributed in the aluminum alloy cylinder 1 with a 50nm thick silica coating 2; the aluminum alloy cylinder is a cylinder; the diameter of the carbon fiber The density of carbon fiber and aluminum alloy is 1.8 g / cubic centimeter and 2.7 g / cubic cm, respectively.

[0025] The preparation method of the above-mentioned carbon fiber composite wire core comprises the following steps:

[0026] A. Immerse the carbon fiber in the silica sol for surface coating, so that the thickness of the cured silica coating is 40-60nm, and then solidify;

[0027] B. Preheating the material obtained in step A to a temperature of 400°C-500°C;

[0028] C. Place the material obtained in step B in a mold, pour the aluminum alloy melt into the mold, squeeze and infiltrate the aluminum alloy melt into the fiber gap, and form it to obtain a carbon fiber composite wire co...

Abstract

The invention discloses a carbon fiber composite lead wire core, a preparation method thereof and a lead wire comprising same. The carbon fiber composite lead wire core comprises an aluminum alloy cylinder and carbon fibers which are uniformly distributed in the aluminum alloy cylinder and provided with silica coating. The lead wire core obtained in the invention is high in strength, has the tensile strength higher than that of a common steel core by about one time and higher than that of a high-strength steel core by 40%, is low in line loss and high in conductivity, has no magnetic loss thermal effect caused by a steel wire material, and has lower operating temperature under the condition of conveying the same load to reduce power transmission loss by about 6%, is small in sag, has significant low sag characteristics compared with a conventional lead wire, and high allowable working temperature, is high in current-carrying capacity, has the aluminum product section of the lead wire with the carbon fiber core being 1.29 times that of a conventional ACSR (Aluminum Conductor Steel Reinforced) under the condition of same quality, is light in weight, has the density of the carbon fibers and the aluminum alloy being 1.8 g/cubic centimeter and 2.7 g/cubic centimeter respectively, and corrosion resistant, with long service life.

Description

technical field [0001] The invention relates to a carbon fiber composite wire core and a preparation method thereof. Background technique [0002] With the rapid development of the national economy in recent years, the demand for electricity has increased rapidly, and the contradiction between the increase in power transmission corridors and the increasingly tense land resources has continued to intensify. How to increase the transmission capacity per unit land area of ​​transmission line corridors and save corridor land , Reducing the impact of transmission lines on the environment and reducing construction investment are issues that must be paid attention to in power infrastructure construction. At the same time, the transmission capacity of some early-built transmission lines can no longer meet the increasing transmission load requirements, and needs to be expanded and reconstructed. Due to factors such as land, routes, demolition and compensation, it is increasingly diff...
