The objective of our study was to evaluate the influence of prolonged artificial ageing on oxidation resistance and the subsequent wear behaviour of vitamin E-stabilized, in comparison to standard and highly cross-linked remelted polyethylene (XLPE), and the degradation effect of third-body particles on highly cross-linked remelted polyethylene inlays in total hip arthroplasty. Hip wear simulat...

Defects inside insulation of HV XLPE cable accessories can lead to partial discharge (PD) activity. When PD activity happens, leakage current may flow through the grounded line. To acquire the PD current signal, one practicable and effective method is placing a high frequency current transformer (HFCT) winding the grounded line. In order to measure the insulation degradation, a partial discharg...

Polyethylene based ionomers are demonstrated to feature a thermo-mechanical and dielectric property portfolio that is comparable cross-linked polyethylene (XLPE), which may enable the design of more sustainable high voltage direct-current (HVDC) power cables, crucial component future electricity grids seamlessly integrate renewable sources energy. A new type ionomer obtained via high-pressure/h...

The space charge dynamic behavior and accumulation are important contributions to the formation of electrical trees, as recognized by crosslinked polyethylene (XLPE) cable insulation under alternating current electric stress. In this paper, in order investigate reasons for phenomenon revealed experiments ac stress, a bipolar transport model with symmetrical asymmetrical parameters is built AC m...

The space charge characteristics of cross-linked polyethylene (XLPE) can be improved to some extent by doping the appropriate amount nano-MgO. In this study, in order explore influence nano-MgO on and electric field distributions composite insulation high voltage direct current (HVDC) cable joints, effect concentration depth density deep traps MgO/XLPE was first analyzed. On basis, transport si...
