In aviation uses, particularly under high-temperature running circumstances, the performance and dependability of wire insulation are very crucial. Maintaining system safety and operational effectiveness in harsh flying conditions depends on long-term insulation integrity being maintained. But conventional assessment techniques may lack the accuracy to replicate continuous thermal stress and fail to identify early-stage insulation breakdown, thereby maybe resulting in system failures. This paper presents the Accelerated Aging and Dielectric Strength Testing (AA-DST) paradigm to go beyond these constraints. This approach more precisely and effectively evaluates insulation durability by combining high-temperature accelerated aging with thorough dielectric strength research. The AA-DST framework simulates real-world aeronautical thermal conditions, enabling a proactive evaluation of insulation breakdown thresholds. The proposed method is applied to a variety of wire insulation materials commonly used in aircraft electrical systems. By subjecting them to elevated temperatures and controlled stress conditions, the AA-DST framework identifies degradation trends and quantifies dielectric strength over time. Findings reveal that AA-DST provides enhanced predictive insights into insulation failure mechanisms, enabling improved material selection and design strategies. This contributes to safer, more reliable electrical systems in aerospace engineering. The proposed method achieves the predictive insights by 97.4%, reliability by 95.8%, material selection by 98.7%.
