The Influence And Analysis Of Heat Conduction On Insulators

Heat is conducted to dead end suspension insulators, causing its surface temperature to rise. This heat accumulation can affect its performance and long-term stability. Conduction is the process of heat diffusing from a high-temperature region to a low-temperature region, typically occurring between polymer deadend insulator and its surrounding environment. When an electric current passes through a conductor, the heat generated during the conduction process is gradually transferred to the insulating material in contact with it. Although the porcelain dead end insulators material is designed to withstand a certain temperature range, continuous heat conduction may reduce its overall performance.

In the design of suspension insulator, the thermal conductivity of the material is precisely controlled to resist the effects of external heat. In power transmission and high-voltage equipment, suspension composite insulator needs to maintain low heat accumulation to prevent overheating from affecting the stable operation of the power system. Heat conduction can accelerate material aging, affecting the long-term service life of composite suspension insulator. In high-temperature environments, increased heat on the surface of polymer suspension insulator can lead to a decline in its electrical performance, and in severe cases, even insulation failure.
