Problems solved by technology

[0003] At present, the power grid engineering cable guide wheels used at home and abroad usually use cast nylon. With the improvement of current requirements, the cable guide wheels formed by cast nylon have the following disadvantages: (1) Large volume and heavy weight (cast nylon The mechanical strength is low. In order to meet the high strength requirements of the cable guide wheel, the cable guide wheel is often designed to be very thick); (2) It is difficult to recycle: the cast nylon has a large molecular weight and high toughness, and it is difficult to recycle; ( 3) The processing and molding cycle is very long and the production efficiency is low
[0005] Although nylon 6 (PA6) resin has many advantages, it cannot fully meet the material requirements of the cable guide pulley, such as the rigidity of the material needs to be improved, the toughness of the material, especially the impact strength under low temperature and dry conditions, and the material's toughness. Scratch resistance needs to be improved, there are technical defects
