Effects of Exposure to Radiation and Steam on Silicone Rubber Cables Removed From a Nuclear Power Plant

open access: yesHigh 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.

Investigation of the Impact of XLPE Cable Ageing on Impedance Mismatch Characteristics and Unbalanced Behaviour in Hybrid Operation Systems

open access: yesHigh Voltage, Volume 11, Issue 2, Page 544-555, April 2026.
ABSTRACT In the Hainan–Guangdong interconnection project, oil leakage in oil‐filled cables required replacing the faulty core with a single core from a three‐core cross‐linked polyethylene (XLPE) cable, leading to mixed operation of XLPE and oil‐filled cables.

Dielectric Loss Suppression of Polyethylene Cable Insulation by Motion Restriction of Ultralow‐Content Grafted Maleic Anhydride

open access: yesHigh Voltage, Volume 11, Issue 2, Page 534-543, April 2026.
ABSTRACT Maleic anhydride (MAH) grafting modification is an effective approach to enhance the insulating performance of polyethylene (PE) cable insulations. However, the high polarity of MAH often causes considerable dielectric loss, making it unsuitable for AC systems.

Combustion Performance of Silicone Rubber Polymer Insulation Material Under Damp‐Heat Ageing Conditions: Molecular Insights Into the Effects of Structural Changes on Macroscopic Properties

open access: yesHigh Voltage, Volume 11, Issue 2, Page 589-599, April 2026.
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

An Experience of Ageing on XLPE Insulation

open access: yesJurnal Teknologi, 2013
A case study of ageing on XLPE conductor insulation of 20kV primary distribution feeder is presented in this paper. The insulation degradation mainly occurred around conductor tie where the conductor is attached to the post insulator. A section of distribution feeder with defects on the conductor insulation has been examined for this study.
