Publish Time: 2024-10-11
In the low-voltage overhead lines of modern power systems, insulators, as key electrical components, not only bear the weight of the conductors, but also play an important role in electrical isolation and mechanical support. Among them, the pressed polymer insulators designed for low-voltage overhead insulated conductors have been widely used in the power industry due to their innovative design and excellent performance. First, the insulator is equipped with a top torque nut, which effectively prevents the loosening or displacement of the conductor during use. Traditional binding methods often make it difficult to ensure the long-term stability of the conductor, while the torque nut provides reliable fixation for the conductor through its tightening characteristics, ensuring the stable operation of the power system.Secondly, the insulator adopts a unique fish mouth design, which not only makes it suitable for both straight and curved lines, but also greatly simplifies the installation process. The fish mouth-shaped opening design allows the conductor to be easily slid in and fixed, greatly saving installation time and labor costs.Furthermore, the ultra-low design of the insulator enables it to effectively resist the beating of the conductor. Under the influence of external factors such as wind, the conductor may vibrate or jump, and the design of this insulator can effectively absorb these vibration energies and ensure the stable operation of the conductor.In addition, there is a wear-resistant gasket inside the insulator, which is designed to prevent the wear of the conductor due to friction during long-term use. The use of wear-resistant gaskets not only extends the service life of the conductor, but also ensures the long-term reliability of the power system.In terms of the fixed area, the insulator is also widened, which effectively prevents the risk of the conductor breaking due to excessive force. The widened fixed area allows the conductor to disperse the pressure more evenly when it is stressed, thereby improving the safety of the entire system.In terms of performance, this insulator also performs well. Its lateral tension is greater than 10KN, and it can withstand wind speeds of up to 50 meters per second, as well as extreme weather conditions such as typhoons and floods. This means that under harsh environmental conditions, the insulator can still maintain its stability and reliability.In addition, the insulator also adopts a buckle design, which effectively avoids the problem of aging, shedding or loosening of the local insulation layer of the wire caused by the heat generated by electrical eddy currents in the traditional binding method. The buckle design not only improves the electrical performance of the insulator, but also ensures the long-term insulation safety of the wire.In terms of weather resistance, the insulator has been directly weathered by the xenon arc lamp method for more than 1,000 hours, and the service life can reach 20 years. This means that during long-term use, the insulator can maintain its good electrical and mechanical properties.Finally, the insulator has also undergone rigorous heat resistance tests. In the test, the diameter of the steel ball indentation was less than 2mm. This result fully proves the stability and reliability of the insulator in high temperature environments.The pressed polymer insulator for low-voltage overhead insulated conductors has shown great application potential in the power industry with its innovative design and excellent performance. With the continuous development of the power industry, this insulator will continue to play its important role and provide strong guarantees for the stable operation of the power system.
