What factors can negatively impact the performance of electrical insulation?

Excessive moisture, heat, and pollution are critical factors that can adversely affect the performance of electrical insulation. When insulation is subjected to high levels of moisture, it can absorb water, leading to a decrease in its dielectric strength and potentially causing short circuits or electrical failures. Heat can accelerate the aging of insulation materials, degrading their structure and effectiveness over time. Additionally, pollutants such as dust, chemicals, and industrial byproducts can create conductive pathways through the insulation or chemically react with the materials, further compromising their integrity. Ensuring a controlled environment free from these elements is essential for maintaining the reliability and performance of electrical insulation systems.
