The composite insulation composed of cross-linked polyethylene (XLPE) and silicone rubber (SiR) is common in high voltage direct current cable accessory installation. However, the space charge accumulation, especially interfacial accumulation XLPE/SiR, poses a serious threat to safe operation accessories, its transport mechanism still unclear, at micro-scale. In order investigate simultaneous m...

During the long-term operation of high-voltage cross-linked polyethylene (XLPE) cables, cable will gradually deteriorate under effect various aging factors. Thermal is one key factors directly related to reliability XLPE cables. In this paper, thermal samples are prepared for PDC measurement. Based on polymer trap theory and extended Debye model, shape curve, depolarization charge, parameters f...

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 polyethylenes are being introduced widely in acetabular cups in hip prostheses as a strategy to reduce the incidence of wear debris-induced osteolysis. It will be many years before substantial clinical data can be collected on the wear of these new materials. Silane cross-linked polyethylene (XLPE) was introduced into clinical practice in a limited series of acetabular cups in 1986...
