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

High Voltage, EarlyView.
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

High Voltage, EarlyView.
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
