Abstract: This study presents estimation of the remaining lifespan of a low-voltage electric cable commonly used in building installations. The cable under investigation is a$\mathbf{1. 5} \mathbf{~ m m}^{\mathbf{2}} \mathbf{4}$-core steel wire armored cable, with cross-linked polyethylene (XLPE) as the primary insulation, and polyvinyl chloride (PVC) used for the bedding and outer jacket. To evaluate the long-term performance of the cable and predict its operational lifespan, accelerated life testing was conducted under controlled thermal stress conditions. The accelerated aging data was then used to develop a life estimation model based on the Arrhenius equation, providing a practical tool to predict the remaining service life of the cable. This approach helps assess the insulation's long-term reliability and supports proactive maintenance strategies to prevent unexpected failures in building electrical networks.
