Abstract:Space charge accumulation in the insulating layers of high-voltage directed current (HVDC) cables is the key factor that leads to their degradation and limits the operation safety. Hence, it is necessary to effectively inhibit carrier implantation to these layers. In this study, a new method is proposed to suppress the charge implantation to the cable insulation layer, a certain amount of Li4Ti5O12 nanopowder is doped in the semiconductive screen to enhance the internal conductive network and homogenize the el… Show more
