Polyethylene (PE), as a widely used cable sheath material, is known for its excellent electrical properties, excellent flexibility and durability. These characteristics make PE cables not only suitable for various complex installation environments, but also ensure long-term stable operation, becoming an indispensable part of modern power transmission systems.First of all, PE cable material performs well in electrical performance. PE has a low dielectric constant and dielectric loss factor, which means that it can effectively reduce signal attenuation and energy loss, and is particularly suitable for high-voltage and ultra-high-voltage power transmission. In addition, PE has high insulation resistance and can maintain stable electrical performance in high temperature or humid environments, avoiding safety hazards caused by leakage or short circuits. This excellent electrical performance not only improves the efficiency of power transmission, but also extends the service life of the cable.Secondly, the flexibility of PE cable material is another significant feature. The molecular chains of PE material are arranged loosely, giving the cable good bending performance, and it can remain soft even in low temperature environments and is not prone to brittle cracking. This feature is particularly important for cables that need to be bent frequently or laid in complex terrain. For example, in an urban underground pipeline network, cables may need to cross multiple bends and obstacles. PE cables, due to their good flexibility, can easily cope with various complex wiring requirements, reducing construction difficulty and cost.Furthermore, the durability of PE cable material is also a highlight. PE material has good impact resistance and wear resistance, and can resist external physical damage to a certain extent. In addition, PE has a smooth surface and a low friction coefficient, which helps to reduce the wear of the cable during dragging. More importantly, PE cables have strong resistance to a variety of chemicals, such as acid and alkali solutions, salt, etc., so they are very suitable for use in highly corrosive environments such as chemical plants and coastal areas. These characteristics work together to enable PE cables to work stably for a long time under harsh conditions, reducing maintenance frequency and replacement costs.It is worth mentioning that PE cable material also shows obvious advantages in environmental protection. PE is a thermoplastic that is easy to recycle and reuse. Compared with some traditional cable materials that are difficult to degrade, PE cables are more in line with the current circular economy concept. At the same time, the production process of PE produces fewer harmful substances and has less impact on the environment, which meets the requirements of green manufacturing. As global attention to environmental protection continues to increase, PE cables are becoming more and more popular due to their environmentally friendly characteristics.In order to further improve the performance of PE cables, researchers are also constantly exploring new modification technologies. For example, by adding nanofillers or adopting blending modification methods, the mechanical strength and weather resistance of PE cables can be further enhanced without sacrificing the original advantages. The application of these new technologies not only broadens the application scope of PE cables, but also provides more possibilities for the upgrading of future power transmission systems.In summary, PE cable material stands out among many cable materials due to its excellent electrical properties, excellent flexibility and durability, and good environmental protection characteristics. Whether facing complex installation conditions or in the pursuit of modern power transmission systems with high efficiency and energy saving, PE cables have demonstrated irreplaceable value. With the advancement of technology and the application of new materials, PE cables will continue to play their important role in helping to achieve a safer, more reliable and sustainable power transmission network.
