Problems solved by technology

[0002] The traditional electric power industry uses ACSR as the main carrier of transmission line to transmit electric energy, but the steel core has the disadvantages of heavy self-resistance, low allowable working temperature, and large line loss, especially low tensile strength and high expansion coefficient. The climate adaptability is poor, so it is a trend to replace steel cores with carbon fiber composite cores. At present, there are two types of carbon fiber composite cores in the domestic market. One is imported cores with good quality but high prices, and the other is domestic cores. , the quality level is low. Therefore, it is imperative to improve the product performance and reach the international level. At the same time, most of the current products are made of glass fiber coated carbon fiber, which has poor torsion resistance and is easy to crack. Therefore, the present invention According to the characteristics of the high-performance resin system, a new manufacturing process of the carbon fiber composite core of the transmission line coated with glass fiber cloth and the outer layer of the carbon fiber composite core with the supporting equipment has been developed.

At present, the production equipment of carbon fiber composite material core produced in China is mainly composed of several parts such as creel, impregnator, yarn guide mold, heater, tractor, winder, etc. The quality of the products produced is low and the speed is low. Low, long cycle, poor comprehensive benefits
