摘要

Dielectric degradation typically originates from local defects. The resulting electric field concentration accelerates defect growth. Suppressing field distortion arising from such local weaknesses has long been a major challenge in electrical insulation. In this work

we incorporated the voltage stabiliser anthrone (ET) into cross-linked polyethylene (XLPE). This design enables field-driven adaptive migration and charge trapping

thereby dynamically regulating local electric fields. Space charge analysis reveals that ET captures charge and creates a reverse electric field. This process inhibits charge injection and transport

significantly reduces internal field distortion and results in a negative electric field coefficient effect. Notably

at 110 kV/mm the distortion ratio decreases from 118.6% in XLPE to only 0.05% in ET/XLPE

a reduction by more than 2000 times. These findings highlight the critical role of voltage stabilisers in enhancing dielectric reliability.
