In low-voltage overhead lines, pressed polymer insulators, as key electrical components, not only bear the heavy responsibility of electrical insulation, but also face the challenges of complex operating environments, among which heat dissipation and temperature control are important factors to ensure stable operation of the line. With the continuous advancement of materials science and electrical technology, pressed polymer insulators have shown unique advantages in efficient heat dissipation and temperature control.Pressed polymer insulators are made of advanced polymer materials and formed through a specific pressing process. This material has excellent thermal stability and thermal conductivity, and can maintain stable electrical performance in high-temperature environments while effectively transferring and dissipating heat. Compared with traditional insulating materials, pressed polymer insulators have lower thermal resistance and higher thermal conductivity, which makes the heat transfer inside and on the surface of the insulator faster and more uniform.In low-voltage overhead lines, the efficient heat dissipation characteristics of pressed polymer insulators are mainly reflected in the following aspects. First, its unique material structure enables heat to be quickly transferred from the conductor to the surface of the insulator, and dissipated to the environment by air convection and radiation. This efficient heat dissipation mechanism effectively reduces the temperature inside the insulator, reducing the risk of material aging and performance degradation caused by high temperature.Secondly, the design of the pressed polymer insulator fully considers the heat dissipation needs. By optimizing the shape and size of the insulator, the contact area with the air is increased, and the heat dissipation efficiency is improved. At the same time, the special treatment of the surface of the insulator also enhances its heat dissipation performance, such as the use of high thermal conductivity coatings or the addition of heat dissipation fins and other structures, which further improves the heat dissipation effect.In terms of temperature control, the pressed polymer insulator also performs well. Due to the excellent thermal stability and thermal conductivity of the material itself, the insulator can maintain stable electrical performance over a wide temperature range. This means that under extreme weather conditions, such as high or low temperature environments, the insulator can effectively resist the impact of temperature changes on line operation.In addition, the pressed polymer insulator also has good weather resistance and anti-aging properties. In long-term operation, it can resist the erosion of natural environments such as ultraviolet rays, wind and rain, and lightning, and maintain its good heat dissipation and temperature control performance. This greatly reduces the risk of line failures caused by aging or damage of the insulator, and improves the reliability and safety of the line.In summary, the pressed polymer insulator achieves efficient heat dissipation and temperature control in low-voltage overhead lines through its unique material structure, optimized design, and excellent thermal stability and thermal conductivity. This not only improves the reliability and safety of the line, but also provides a strong guarantee for the stable operation of the power system. With the continuous advancement of technology and the continuous expansion of application fields, pressed polymer insulators will play a more important role in low-voltage overhead lines in the future.
