Significant Suppression of High Electric Field Regions in XLPE via Voltage Stabilisers

High Voltage
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.
