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

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.

Space Charge in Electron-Beam Irradiated Cross-Linked Polyethylene (XLPE): Charge Implantation and Release from the Bulk [PDF]

2019 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2019
The aim of the present work is to study the dynamics of the space charge in crosslinked polyethylene (XLPE) induced by electron beam irradiation. For this purpose three energies have been chosen so as to implant charges in a controlled way, in the volume, at different depths not too close to the electrodes. Pulsed Electro Acoustic (PEA) method was used

Correlation of traps inside XLPE and polypropylene with space charge dynamics under polarity reversal condition

IET Science, Measurement & Technology, 2021
Polypropylene (PP) is being considered as a suitable alternative to the cross‐linked polyethylene (XLPE) insulation as the latter is prone to the space charge accumulation when subjected to the voltage polarity reversals in line‐commutated converter high

High‐Temperature and Chemically Resistant Protein Material with Electric Insulation Properties Comparable to Todays Fossil‐Based Plastics

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.

Understanding the Mechanism of Junction Effect of Homo‐Bilayer XLPE for HVDC Cable Factory Joints

High Voltage
In high‐voltage direct current cable systems, the factory joint of cross‐linked polyethylene (XLPE)‐insulated cables presents significant electrical breakdown risk. The charge accumulation mechanism at the XLPE–XLPE interface involves the accumulation of
