🔍 Key Concepts

• Thermal stress on electrical insulation – how heat affects materials over time • The common engineering rule-of-thumb relating temperature rise to insulation life • The idea of an accelerated aging effect when components run hotter than designed

💭 Think About

• If a material is operated hotter than its design temperature, does it usually last longer or shorter? By what kind of factor? • Think about why manufacturers specify maximum operating temperatures for wire and cable insulation – what typically happens to life when you exceed that by 10°C? • Is the effect of temperature on insulation life usually considered random, or is there a predictable trend used in design calculations?

✅ Before You Answer

• Recall the widely used rule-of-thumb: for many insulating materials, a 10°C change corresponds to about a 2× change in life – think about whether that is an increase or decrease in life when temperature goes up. • Eliminate options that contradict the idea that higher temperature increases chemical and thermal degradation rates. • Consider whether professional standards and design guides treat this relationship as predictable or unpredictable.
