Carbon fiber composite material cable and preparation method of cable core thereof

Abstract

The invention discloses a carbon fiber composite material cable and a preparation method of a cable core of the carbon fiber composite material cable. The preparation method comprises the following steps: testing and adjusting the tensile forces of carbon fibers and glass fibers; dewatering; pulling the carbon fibers into a procuring die (3) by infiltrating adhesive in a constant temperature adhesive groove; operating the glass fibers to pass through a rectangular splitting plate (4); pulling the carbon fibers into a curing die (5); feeding the glass fibers through a planar guide plate (6), and then puling into the curing die (5) so as to wrap the surrounding parts of the carbon fibers with the glass fibers, thus obtaining the carbon fiber composite material cable core. The method provided by the invention has high operability and relatively high production efficiency, can saves large amount of manpower and materials, and has low cost of production; and the carbon fiber composite material cable core prepared by the method has relatively high linearity, high roundness, no eccentricity, no bending, and high consistency in color; and as the detecting results shown, the carbon fiber composite material cable core has the advantages of high temperature resistance, lower energy consumption, long service life, no eccentricity, and good performance.

Description

technical field [0001] The invention relates to a cable core, in particular to a carbon fiber composite cable and a preparation method for the carbon fiber composite cable core. Background technique [0002] For a long time, the wires and cables used in long-distance large-capacity power transmission generally use steel-cored aluminum stranded wire as the conductor, which not only consumes a lot of energy, but also has a small current carrying capacity. The resulting power outages and power failures occur from time to time, which has become the development of the power industry. A big "bottleneck". With the continuous progress of material technology, at the end of the 20th century, people tried to use organic composite materials instead of metal materials to make the core material of the wire, and developed a new composite material synthetic core wire. This kind of wire has the characteristics of high temperature resistance, large capacity, low energy consumption and long l...

AI Technical Summary

Problems solved by technology

However, the existing carbon fiber composite material cable cores often have the following problems in the manufacture: 1. The molds of the prior art are seriously damaged during the production process, cannot be produced continuously for long distances, and the production efficiency is low, requiring a lot of manpower and material resources, and the cost is high; 2. The mandrel carbon fiber prepared by the current process often has eccentric defects and poor quality; 3. The mandrel prepared by the current process is not straight and has a large curvature, which affects performance; 4. There are many shortcomings such as differences in the color of the mandrel.
