Effects of combined UV-tensile aging on structural and electrical properties of high temperature vulcanized silicone rubber in composite insulators

Key Points

• Combined UV and tensile stress significantly degrades silicone rubber properties.
• The aging process shows interactions like molecular scission and oxidative crosslinking.
• Silicone rubber degradation affects the performance of composite insulators over time.
• Understanding these effects can lead to better material design in high-temperature applications.
