A concise kinetic model catering for the antioxidant reaction of thermally aged cross-linked polyethylene (XLPE) cable insulation before its abrupt performance deterioration is proposed life prediction and condition assessment. The alternating current breakdown strength, elongation at break, carbonyl index, pyrolysis activation energy XLPE are found to consistently display an change a certain p...

Cross-linked polyethylene (XLPE) cables are widely used in the distribution and transmission networks of power systems. The insulation materials these stressed by over voltages also exposed to various environmental conditions. This leads degrade during their normal life span. Therefore, it would be advantageous for utilities acquire cable’s condition frequently operation. In this paper, experim...

Abstract The buffer layer defects of high‐voltage crosslinked polyethylene (XLPE) cable occur frequently, which makes the detection method become focus to be studied. Here, broadband impedance technology for XLPE cables with corrugated aluminium sheath is investigated. There are nine samples, including new and defective ones. Some artificial, other retired cables. influence wiring mode, circumf...

The present work deals with the study of electrical behavior cross-linked polyethylene (XLPE) used for HVDC cable insulation. aim is to better understand influences and thermal stresses on insulating material in order provide useful information designing cables. This was carried out Rogowski samples made XLPE insulation semiconductive electrodes, aged more than 3 years (1220 days) at three diff...

The application of cross-linked polyethylene (XLPE) cables to voltage sourced converter (VSC)-based high direct current (HVDC) systems has already been technically verified and become common, thermoplastic (TP) is attracting attention as an insulation material for next-generation due the recent development material-related technologies. However, studies related TP are mainly focused on improvin...
