As an environmentally friendly polymer material, isotactic polypropylene (pp), possesses excellent dielectric properties while it can be recycled, so is regarded as having promising application prospects in the field of high voltage power cable insulation. However, increasing operating rating also puts higher demands on its insulation reliability. In this study, intrinsic modulation method for pp based mesoscopic structure by crystal phase transformation proposed, which not only effectively...

This article focuses on the effect of polarity reversal space charge behavior and electric field evolution ±500-kV HVDC cables under different temperature gradients. A modified bipolar electronic-ionic transport (BEICT) model XLPE insulation considering dissociation impurities is established for full-sized cables. The results demonstrate that increase in gradient accelerates injection migration homocharge vicinity inner semi-conductive layer dc voltage, which leads to a higher immediately...
This paper focuses on the space charge and electric field characteristics in extrusion molded joint (EMJ) for ±500 kV HVDC submarine cables. The double-layered XLPE samples are prepared to imitate insulation interface EMJ, assessed utilizing pulsed electro-acoustic (PEA) method. Then, a two-dimensional simulation model based modified BCT containing ionic charges is established. results demonstrate that outcomes exhibit consistency with experimental observations by measuring mobilities trap...
