The effect of degassing on morphology and space charge

, 2004
It is believed that space charge buildup in cross-linked polyethylene (XLPE) insulation is the main cause for premature failure of underground power cables. The space charge activities in XLPE depend on many factors such as additives, material treatment,

The effect of surgeon’s preference for hybrid or cemented fixation on the long-term survivorship of total knee replacement: An analysis of 39,623 prostheses from the Australian Orthopaedic Association National Joint Replacement Registry

Acta Orthopaedica, 2018
Background and purpose — Recent direct comparative reports suggest that hybrid fixation may have a similar or superior outcome to cemented fixation in total knee replacement (TKR); however, a paucity of long-term data exists.

Effect of Aggregation Structure on DC Electrical Performance of Thermo‐Oxidatively Aged Crosslinked Polyethylene Insulation

High Voltage, Volume 11, Issue 1, Page 49-59, February 2026.
ABSTRACT Thermal ageing is an important factor leading to the deterioration of crosslinked polyethylene (XLPE) cable insulation. In this paper, XLPE insulating material was prepared in the laboratory and treated by thermal ageing at 130°C for durations of up to 40 days.

Performance Evolution and Ageing Characteristics of Crosslinked Polyethylene Insulation for HVDC Cables After Field Operation

High Voltage, Volume 11, Issue 1, Page 60-72, February 2026.
ABSTRACT The ± 200 kV direct current (DC) cables of the Zhoushan Transmission Project were targeted, and crosslinked polyethylene (XLPE) insulation samples were prepared from faulty and spare cables. Samples were tested for oxidation induction period, Fourier transform infrared spectroscopy, differential scanning calorimetry, thermally stimulated ...

Quantitative Measurements of Backside Wear in Acetabular Hip Joint Replacement: Conventional Polyethylene Versus Cross-Linked Polyethylene

, 2020
As shown in previous studies, the modification of conventional polyethylene (CPE) to cross-linked polyethylene (XLPE) and the contribution of antioxidants result in a reduction in total wear.

Experiments and Simulations on the Equivalence of Pre‐Cross‐Linking in Cable Insulation Material Extrusion

High Voltage, Volume 11, Issue 1, Page 37-48, February 2026.
ABSTRACT The rheological properties of cable insulation materials are critical to the long‐term continuous extrusion performance of high‐voltage cables, with the pre‐cross‐linking effect playing a key role in determining the rheological behaviour of the insulation material during extrusion.
