What is the Role of Carbon Fiber in the Development of China’s Electricity
Carbon fiber has the characteristics of solid carbon, strength and toughness, and it has the properties of soft and machinable fiber. It is a new kind of multi-purpose material. In the field of electric power, the invention of the core rod of carbon fiber composite core has broken the Western technology fort and changed the current situation of the transmission field in China, which is a revolutionary progress.
Carbon fiber composite core wires have great advantages, including high temperature resistance, corrosion resistance, high strength, low density and high conductivity. Its strength is more than 2 times higher than that of high strength steel wire, and its tensile property is very good. It can not only guarantee the normal transmission of electric power, but also improve the safety quality. At high temperature, due to the principle of thermal expansion and cold contraction, the original twisted wire will bend to produce the radian. Although the carbon fiber composite core conductor will also be like this, it will be less than 1/10 of the bending strength compared with the steel reinforced aluminum conductor.
In this way, the distance between the poles can be properly increased, and the height can be reduced appropriately, and the material is saved. In some places, the weather is bad, the circuit structure is easily damaged and the power supply is difficult. Carbon fiber composite core wire, whether in the hot sun or ice and snow, can be used for a long time, very durable. In addition, carbon fiber composite core wires, unlike steel wires, are magnetic structures, and do not cause hysteresis and eddy current effects.
At present, the carbon fiber composite core conductor has been listed as a key project in the national grid. Many large enterprises have heard of cooperation, and nationwide popularization is just around the corner. The discovery of carbon fiber composite core conductors has greatly promoted the development of China’s electric power industry and thus promoted the development of the economy. Technology changes life and believes that more use of carbon fiber can be found in the future.
