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.

High 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.

Insulation Degradation Diagnostic Technology to XLPE Cable
IEEJ Transactions on Fundamentals and Materials, 2004 XLPE power cables have been in use for long time now and some of them are approaching 30 years of their designed lifetime. However, under the present severe economic situation, it is necessary to use the existing apparatus as long as possible. So, degradation diagnostic methods with high reliability are needed earnestly.

Advanced Sustainable Systems, Volume 10, Issue 3, March 2026.Thermally treated wheat gluten‐based materials have the potential to be used as low‐voltage electric insulation in e.g. electric motors. A future implementation of these types of protein materials enables a balance between performance and sustainability (from fossil‐based to biobased materials) in e.g. automotive applications.
