Key Points

This research aims to investigate the effects of thermal and mechanical stresses on silicone rubber and XLPE used in high-voltage cable accessories.
Conducted thermomechanical analysis on silicone rubber and XLPE samples.
Simulated harsh mechanical and thermal stress conditions.
Evaluated changes in mechanical properties over time.
Silicone rubber and XLPE showed significant deterioration under stress.
Mechanical properties declined, indicating reduced reliability over time.
Findings suggest a need for improved materials in cable accessories.

Implication

Analysis uncovers deterioration in mechanical properties of cable accessories, indicating reliability issues.

Abstract

Medium and high-voltage cable accessories, such as terminations and connectors, operate under harsh mechanical and thermal stresses, influencing long-term reliability. These stresses may lead to deterioration in the mechanical properties...
