Pressed Polymer Insulators For Low Voltage Overhead Insulated Conductors are key components in the power system. Their main function is to support and insulate low-voltage overhead conductors to ensure stable and safe transmission of electricity.1. Materials and structuresPressed polymer materials:Polymer insulators: Polymer insulators made by pressing are mainly made of high-strength polymers (such as silicone rubber, polyurethane, etc.), which have excellent insulation performance and durability.Environmental resistance: Polymer insulators have strong resistance to UV, aging and chemical corrosion, and can maintain stable performance under severe weather and environmental conditions.Structural design:Compact structure: Insulators are usually designed with a compact structure, which can effectively support the conductor and ensure its stability, while reducing the impact of wind loads and other mechanical stresses on the conductor.Surface design: The surface usually has a special texture or coating to increase anti-fouling ability and self-cleaning function, and reduce the attenuation of insulation performance.2. Stability and durabilityHigh-strength support:Carrying capacity: Polymer insulators are designed to withstand high-strength mechanical loads, including the weight of the conductor, wind pressure, and ice and snow loads, ensuring stable operation of the conductor under various environmental conditions.Vibration resistance: High-quality polymer insulators have good vibration resistance and can cope with vibrations caused by wind and current to prevent the conductor from loosening or breaking.Aging resistance:Long life: Polymer materials have excellent aging resistance and can maintain their insulation performance and mechanical strength during long-term use, reducing the need for frequent replacement.Stability: After a long period of practice, it has been proven that these materials are stable under various climatic conditions (such as high temperature, low temperature, and humid environment), maintaining the long-term operation of the power system.3. Electrical performanceExcellent insulation performance:High insulation strength: Polymer insulators have high insulation strength, which can effectively prevent current leakage and ensure stable power transmission.Low leakage current: Through high-quality insulation materials and good insulation design, leakage current is reduced, reducing power loss and the risk of electrical failure.Anti-pollution:Self-cleaning function: The surface design of polymer insulators has a self-cleaning function, which can effectively remove accumulated dirt and maintain the stability of insulation performance.Pollution voltage: The ability to resist pollution reduces the problem of pollution voltage caused by dirt accumulation and ensures the safe operation of the power system.4. Maintenance and operationLow maintenance requirements:Durability: Due to the durability and stability of polymer insulators, maintenance requirements are low, reducing the frequency of maintenance and inspections, thereby reducing operating costs.Easy to install: The installation of insulators is usually simple and quick, reducing installation time and labor intensity, ensuring rapid commissioning.Safety:Anti-electric shock: Polymer materials have excellent insulation properties, effectively preventing the occurrence of electric shock accidents and ensuring the safety of workers and the public.Mechanical safety: The sturdy structural design reduces safety hazards caused by equipment failure or mechanical damage.5. Environmental adaptabilityAdapt to extreme climates:High and low temperatures: Polymer insulators can maintain stable performance under extremely high and low temperature conditions, ensuring the normal operation of the power system under various climatic conditions.Humidity and corrosion: It has good resistance to humidity and corrosion, and is suitable for humid and corrosive environments.Pressed Polymer Insulators For Low Voltage Overhead Insulated Conductors, through its excellent material properties, stable structural design, electrical performance and adaptability to the environment, can effectively protect the long-term operation of the power system. Its solid stability not only ensures the stable transmission of electricity, but also reduces maintenance costs, improves the safety and reliability of the power system, and is an indispensable component in modern power systems.
