In the power system, low-voltage overhead insulated conductors play a vital role. They are responsible for safely and efficiently transmitting electrical energy to thousands of households. As an important component of the conductor, the pressed polymer insulator provides solid support for the stable operation of the power system with its unique performance characteristics.As the name suggests, the pressed polymer insulator is an insulating component that is formed by processing polymer materials through a pressing process. This insulator is widely used in low-voltage overhead insulated conductors and has won wide recognition for its excellent electrical and mechanical properties.From the perspective of electrical performance, the pressed polymer insulator has extremely high insulation resistance and breakdown voltage. This means that under normal operating conditions, the insulator can effectively prevent the passage of current and ensure electrical isolation between the conductor and the bracket or other metal parts. This feature is crucial to preventing electrical faults such as leakage and short circuit, and can effectively ensure the safe operation of the power system.At the same time, the pressed polymer insulator also has excellent weather resistance. Whether it is hot summer or cold winter, the insulator can maintain stable performance and is not affected by temperature changes. In addition, it also has excellent anti-aging properties and can maintain its original mechanical strength and electrical properties in long-term wind and sun exposure.In terms of mechanical properties, the pressed polymer insulator also performs well. It has high strength and toughness, and can withstand the mechanical stress of the wire caused by wind force, temperature changes and other factors. In addition, the surface of the insulator has been specially treated with good anti-slip properties, which can effectively prevent the wire from swinging and jumping in the wind, and reduce the risk of electrical failure caused by wire dancing.In addition to the above performance characteristics, the pressed polymer insulator also has the advantages of small size, light weight and easy installation. These characteristics make the insulator more convenient during transportation, installation and maintenance, reducing the difficulty and cost of construction. At the same time, the insulator has a long service life, which can reduce the frequency of replacement and further reduce the maintenance cost.In addition, the pressed polymer insulator also has good environmental performance. The polymer material it uses can be recycled and reused, which is in line with the concept of sustainable development. When the power facilities are replaced, the insulator can be recycled and processed into new products, reducing pollution to the environment and waste of resources.In summary, the pressed polymer insulator in low-voltage overhead insulated conductors plays a vital role in the power system with its excellent electrical properties, mechanical properties, weather resistance, environmental protection performance and easy installation. In the future, with the continuous development and progress of power technology, it is believed that the pressed polymer insulator will be more widely used and promoted, providing more reliable guarantee for the stable operation of the power system.
