Embodiment 1

[0030] Such as figure 1 shown.

[0031] A carbon fiber composite stranded wire reinforced core cable for transmission lines, which is composed of a core wire 1 acting as a load bearing and at least one layer (two layers in the figure) of a conductive metal wire 2. The core wire 1 is wrapped in a metal In the conducting wire 2, the core wire 1 is composed of a plurality of carbon fiber composite cores 3, and each strand of the carbon fiber composite core is obliquely twisted and bonded into one body. Between the surface of the carbon fiber composite stranded wire core and the aluminum conductor, there is a protective layer 4 of glass fiber tape for insulation. The core wire 1 is composed of at least seven carbon fiber composite cores 3 with a diameter of not less than 1 mm; the angle between each carbon fiber composite core 3 and the axis is not greater than 10 degrees. The metal wire 2 is an aluminum wire, which is obliquely extruded and wrapped around the core wire 1 by a p...

Embodiment 2

[0033] A method for preparing a carbon fiber composite stranded wire reinforced core cable for transmission lines, comprising the following steps:

[0034] First, set the tension creel equal to the number of strands of the composite stranded wire, pull the carbon fiber out at a constant speed from each tension creel with tension display and centralized control of tension, and control the tension at 1~5kN;

[0035] Secondly, the carbon fiber on each tension creel is led out, the yarn is collected by the yarn collector to form a fiber bundle, and then introduced into a cycle oven to remove broken fibers floating on the surface of the fiber bundle to increase the volume ratio of continuous carbon fiber in the product and remove the fiber The moisture content in the fiber should be controlled to less than 3%, and the temperature of the cycle oven should be controlled at 400°C~500°C;

[0036] The third step is to send the dehumidified carbon fiber into the corresponding constant te...

Abstract

The invention discloses a cable with a composite carbon fiber stranded wire reinforced core for a power transmission line and a manufacturing method thereof. The cable consists of a core wire (1) with a load bearing function and at least one layer of metallic conductor (2) with a conductive function, wherein the core wire (1) is wrapped in the metallic conductor (2). The cable is characterized in that: the core wire (1) consists of a plurality of strands of carbon fiber composite cores (3), wherein the carbon fiber composite cores (3) are obliquely twisted and bonded into a whole. The cable provided by the invention has light specific weight, strong strength, resistance to high temperature, corrosion resistance, low line loss, low sag and a low thermal expansion coefficient.

Description

technical field [0001] The invention relates to a power transmission line cable, in particular to a cable using a composite material as a core wire and a preparation method thereof, in particular to a power transmission line carbon fiber composite strand reinforced core cable and a preparation method thereof. Background technique [0002] Since 1800, there have been few major innovations in the wires used for overhead power transmission. Among them, steel-cored aluminum wires have been used the most, as the steel strands that bear the weight of overhead power transmission cables. Magnetic loss and thermal effects cause the line loss of the output line. In addition, the tensile strength of the steel strand is not high. In 2008, a large area of ​​output towers in southern my country collapsed and the power supply line was paralyzed because the steel strand could not bear the weight of ice and snow. The tower collapsed. For this reason, according to the characteristics of comp...
