Impact of mechanical deformation on space charge in XLPE [PDF]

, 2007
In this paper we report the effect of mechanical deformation on space charge dynamics in crosslinked polyethylene. Thin films were peeled from a 66 kV commercial XLPE cable. Space charge measurements under dc electric fields have been monitored using the

Experimental investigation of E-beam effect on the electric field distribution in cross-linked polyethylene/ZnO nanocomposites for medium-voltage cables simulated by COMSOL Multiphysics

Journal of Analytical Science and Technology, 2022
This study investigated the electric field distribution of underground cable insulation in cross-linked polyethylene/zinc oxide (XLPE/ ZnO) nanoparticles (NPs) for medium-voltage (MV) cables. The ZnO NPs that were obtained by three methods of preparation

Algorithm for load cycling correction to minimise the dry zone influences on the cross‐linked polyethylene (XLPE) cable insulation [PDF]

IET Generation, Transmission & Distribution, 2020
Dry zone formation around underground power cables during load cycling may lead to thermal failure of the cable's insulation. This phenomenon has to be recorded to send an alarm to the maintenance crew when the soil around the cable reaches the critical value at which the dry zone has started to be formed.

Current‐Carrying Characteristics of High‐Voltage Land Cables With Different Grounding Methods for Low‐Frequency AC Transmission

High Voltage, EarlyView.
ABSTRACT Low‐frequency AC transmission holds promise for high‐voltage land cables, but its ampacity is significantly influenced by cable grounding methods and other structural factors. To explore the specific low‐frequency current‐carrying characteristics of high‐voltage land cables, this paper conducts a thorough theoretical analysis of the coupling ...

Current‐Generation Crosslinked Polyethylenes for Total Hip Arthroplasty: Mechanistic Insights Into Oxidative Stability and Antioxidant Efficiency

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 7, July 2026.
ABSTRACT Highly crosslinked polyethylene (XLPE) has revolutionized total hip arthroplasty (THA), but increased radiation doses and complex crosslink structures may increase oxidation susceptibility. The long‐term oxidative stability of XLPE depends on manufacturing factors, including crosslink density, antioxidant (vitamin E) concentration ...

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

Advanced Functional Materials, Volume 36, Issue 30, 13 April 2026.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...
