Dielectric strength is a crucial property of insulating materials, determining their ability to withstand electrical stress without breaking down. It represents the maximum electric field an insulator can endure before electrical breakdown occurs. Measured in volts per unit thickness, typically volts per millimeter (V/mm), dielectric strength varies among materials. Factors influencing dielectric strength include material composition, thickness, temperature, humidity, and applied voltage duration. Understanding dielectric strength is essential for selecting appropriate insulating materials in electrical and electronic applications, ensuring safety and reliability in various industries such as power transmission, electronics manufacturing, and aerospace.

The insulation performance of insulating materials is intricately linked to temperature, playing a pivotal role in their effectiveness across various applications. As temperature fluctuates, the thermal conductivity of insulating materials can change significantly, impacting their ability to resist heat flow. This temperature-dependent behavior is crucial for engineers and designers when selecting appropriate insulation for specific environments. Understanding this relationship allows for optimal insulation system design, ensuring energy efficiency and thermal comfort in buildings, industrial processes, and numerous other scenarios where maintaining desired temperatures is paramount.
