As a key component connecting copper and aluminum conductors in the power system, the structural strength of the new copper-aluminum transition clamp is directly related to the safety and stability of the entire power grid. By adopting the cold extrusion forging process of T2 copper rods, this wire clamp not only has significant advantages in material selection, but also greatly improves its structural strength and reliability during the manufacturing process, ensuring the long-term safe and stable operation of high-voltage lines.First of all, T2 copper rods themselves are a high-purity oxygen-free copper material, known for their excellent conductivity, good mechanical properties and corrosion resistance. However, relying solely on high-quality raw materials is not enough to meet the strict requirements of modern high-voltage power systems. In order to further improve the density and structural strength of the material, the cold extrusion forging process has become the key. Compared with traditional hot processing methods, cold extrusion forging is carried out at room temperature, which can effectively avoid problems such as oxidation and decarburization that may occur during high-temperature treatment, and maintain the original pure state and excellent performance of the material. At the same time, the high pressure in the cold extrusion process makes the metal grains more fine and uniform, greatly enhancing the overall strength and toughness of the material. This microstructural optimization provides a solid foundation for the wire clamp, enabling it to operate stably and for a long time in a complex and changing working environment.Secondly, the role of the cold extrusion forging process in improving the structural strength of the wire clamp is also reflected in its unique forming method. During the cold extrusion process, the T2 copper rod is placed in the mold, and the metal is plastically deformed by applying huge pressure to finally form the desired shape and size. During this process, the internal structure of the metal undergoes a drastic reorganization, and the original grain boundaries are broken and rearranged to form a more compact crystal structure. This structure not only has higher tensile strength and hardness, but also has better ductility and toughness. Therefore, even when the wire clamp is subjected to greater mechanical stress or external impact, it can effectively prevent cracks from occurring and expanding, greatly reducing the risk of fracture. For high-voltage power lines, this means a more reliable connection point, reducing power outages caused by joint failures, and ensuring the continuity and safety of power supply.Furthermore, the cold extrusion forging process also brings another important advantage, which is to improve the surface quality and precision of the wire clamp. Because the process is carried out under precisely controlled pressure and temperature conditions, very high dimensional tolerances and surface finish can be achieved. This not only helps to ensure the perfect fit between the wire clamp and other components, but also reduces contact resistance and improves electrical performance. Specifically, after cold extrusion, the inner and outer surfaces of the wire clamp are very smooth and flat, without burrs or irregular edges. These improvements in details make the contact between the wire clamp and the wire closer, reduce energy loss during current transmission, and improve overall efficiency. In addition, the high-quality surface treatment also provides an ideal base for the subsequent anti-rust and waterproof coating, further enhancing the durability and protection of the product.It is worth mentioning that the new copper-aluminum transition clamp fully considered the various challenges in practical applications during the design stage. For example, in response to the common copper-aluminum interface contact problem of traditional wire clamps, the R&D team innovatively used the V-groove process to process the inner wall of the copper sleeve, and combined with high-pressure die-cast aluminum welding one-piece molding technology to achieve seamless connection. This design not only increases the copper-aluminum contact area, but also eliminates potential defects such as air cavities, fundamentally solving the problem of excessive connection resistance. At the same time, the cold extrusion forging process gives the wire clamp excellent mechanical properties, enabling it to better adapt to complex working conditions, whether it is extreme climatic conditions or frequent operating loads, it can perform well. This comprehensive optimization design makes the new copper-aluminum transition clamp show extremely high reliability and stability in practical applications.In addition, from the perspective of the manufacturing process, the cold extrusion forging process also has significant environmental benefits. Compared with traditional hot processing methods, cold extrusion does not require a lot of energy to heat the metal, thereby reducing the emission of carbon dioxide and other pollutants. In addition, due to the high material utilization rate in the cold extrusion process, the amount of waste is relatively small, which further reduces resource waste. This is of great significance for promoting green manufacturing and achieving sustainable development goals. At the same time, efficient production processes also mean lower cost investment, providing users with more cost-effective options. It can be said that the new copper-aluminum transition clamp has not only reached new heights in technology and performance, but also performed well in terms of economy and environmental protection.Finally, the success of the new copper-aluminum transition clamp is inseparable from advanced production equipment and technical support. Modern cold extrusion machines and precision molds ensure that every production link can meet the highest standards. Strict quality inspection processes run through the entire production process, from raw material detection to finished product inspection, and each indicator is carefully checked to ensure the stability and consistency of product quality. It is this unremitting pursuit of quality that has made the new copper-aluminum transition clamp win wide recognition and trust in the market and become the preferred product for many power engineering projects.In summary, the new copper-aluminum transition clamp has achieved remarkable results in improving structural strength by adopting the T2 copper rod cold extrusion forging process. From enhancing material density and refining grain structure, to optimizing surface quality and increasing copper-aluminum contact area, to reducing energy consumption and improving environmental protection performance, every link reflects the power of technological innovation. This high-performance transition clamp not only provides a solid guarantee for the efficient operation of the power system, but also lays a good foundation for future development. With the continuous advancement of technology and changes in market demand, it is believed that the new copper-aluminum transition clamp will continue to play an important role in helping the power industry move towards a more intelligent and reliable new era.
