The effect of degassing on morphology and space charge
, 2004 It is believed that space charge buildup in cross-linked polyethylene (XLPE) insulation is the main cause for premature failure of underground power cables. The space charge activities in XLPE depend on many factors such as additives, material treatment,

High Voltage, Volume 11, Issue 2, Page 410-420, April 2026.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 ...

High Voltage, Volume 11, Issue 2, Page 482-493, April 2026.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.
