ABSTRACT Cross‐linked polyethylene (XLPE) cables play an important role in power systems to transport electrical energy, and moisture is one of the important predisposing factors for insulation failure in medium and high‐voltage cables. In this paper, a temperature‐moisture accelerated ageing experiment is designed, and a method for assessing the ...

ABSTRACT Low‐voltage cables insulated with silicone rubber were harvested from three locations in the primary containment vessel of a boiling water nuclear power plant (NPP). Subsequently, the cable, which was placed in an ambient environment with a relatively higher temperature and the highest rate, was cut into four shorter ones.

ABSTRACT Silicone rubber (SR), an organic silicon polymer material, is known for its excellent heat resistance and mechanical properties. It is widely used in composite insulators and cable accessory materials. However, the ageing caused by humidity and heat significantly impacts its performance, an issue that cannot be ignored. This paper investigates
