DP value quantifies aging; Arrhenius model predicts lifespan (every 6-10°C rise doubles aging rate).
1. Aging Mechanism: Heat, moisture, oxygen, and acidity break cellulose chains; DP decline reduces mechanical/electrical strength.
2. DP Criteria: >1000 (Excellent), 500-1000 (Good), 250-500 (Degraded, plan maintenance), <250 (End of life, replace immediately).
3. Life M...
