Space charge is one of the main causes of electrical tree initiation in high-voltage cable insulation. To investigate the influence of DC pre-stress on the space-charge distribution of cross-linked polyethylene (XLPE). a two-dimensional needle-plate electrode model is established in this study. Based on the bipolar charge-transport model. https://www.markbroyard.com/special-pick-igora-vibrance-6-0-dark-blonde-natural-supply-best-super/
