The Need for Multi-Factor Aging Tests
In the field, insulators never experience a single stress in isolation. Rain, UV, pollution, voltage, and temperature cycling all act simultaneously. Single-factor aging tests can miss synergistic degradation mechanisms that only appear when multiple stresses interact. The multi-factor aging device addresses this by applying all relevant stresses concurrently.
Research Applications
Multi-factor aging systems are particularly valuable for R&D evaluation of new housing materials, coating formulations, and insulator designs. They provide the most realistic accelerated aging data for predicting 25-40 year service life performance.
