Performance of pressed polymer insulators for low voltage overhead insulated conductors in natural disasters
Publish Time: 2025-05-06
With the impact of global climate change, the frequency and intensity of natural disasters such as earthquakes, strong winds, heavy rains and floods are increasing. The stability and reliability of power transmission systems are essential to ensure the normal operation of society. As a new type of insulation equipment, pressed polymer insulators for low voltage overhead insulated conductors have shown excellent performance in the face of natural disasters.1. Earthquake resistance: Stable support of the power gridEarthquakes are one of the main natural disasters that cause damage to power facilities. Traditional ceramic insulators are prone to cracking or falling off during earthquakes due to their brittleness, causing line failures. In contrast, pressed polymer insulators for low voltage overhead insulated conductors have excellent toughness and impact resistance. Its material properties enable it to absorb and disperse vibration energy, thereby reducing mechanical damage caused by earthquakes. In addition, pressed polymer insulators for low voltage overhead insulated conductors are usually designed with special mounting structures that can be better fixed on the tower to ensure stability under strong vibrations.2. Wind resistance: resist strong windsStrong winds often cause overhead lines to swing more and even cause line breaks. Pressed polymer insulators for low voltage overhead insulated conductors can effectively resist wind force due to their light weight and high strength. Not only are they lightweight, reducing the load on the tower, but they are also flexible and can bend moderately under wind force without breaking easily. In addition, some high-end models are equipped with windproof devices to further enhance wind resistance and ensure that power transmission lines remain safe and reliable under strong wind conditions.3. Weather resistance: cope with extreme climatic conditionsWhether it is high temperature, low temperature or humid environment, pressed polymer insulators for low voltage overhead insulated conductors can perform well. Its materials have been specially treated to have excellent weather resistance and can maintain stable physical and electrical properties over a wide temperature range. For example, in extremely cold regions, pressed polymer insulators for low voltage overhead insulated conductors will not crack due to sudden temperature drops like ceramic insulators; in tropical rainy regions, they can also effectively prevent moisture penetration and avoid insulation failure caused by moisture.4. Flood resistance: Protect power facilities from water damageFlood disasters not only directly destroy power infrastructure, but also cause equipment damage through immersion. Pressed polymer insulators for low voltage overhead insulated conductors are waterproof and made of materials with good waterproof properties, which can resist floods to a certain extent. Even if they are submerged for a short time, their insulation performance will not be affected. In addition, the surface of pressed polymer insulators for low voltage overhead insulated conductors is smooth and not easy to adhere to mud and other debris, which is convenient for post-disaster cleaning and maintenance, and rapid restoration of power supply.5. Anti-ultraviolet and aging: Extend service lifeLong-term exposure to outdoor environments, ultraviolet radiation will cause aging and performance degradation of insulators. The surface of pressed polymer insulators for low voltage overhead insulated conductors is usually coated with an anti-ultraviolet coating, which can effectively block the damage of ultraviolet rays to the material and delay the aging process. At the same time, this material itself has good antioxidant ability. Even under long-term exposure to the sun and rain, it can maintain the original mechanical strength and electrical insulation performance, significantly extending the service life of the product.In summary, pressed polymer insulators for low voltage overhead insulated conductors have shown strong adaptability and protection effects in the face of various natural disasters due to their excellent earthquake resistance, wind resistance, weather resistance, flood resistance and aging resistance. It not only improves the overall stability of the power transmission system, but also provides a solid foundation for ensuring the continuity of social and economic activities.
