Improved DC Properties of Polypropylene HVDC Cable Insulation by Grafting and Blending Combined Modification

open access: yesHigh Voltage, EarlyView.
ABSTRACT In order to meet the needs of mechanical properties of cable insulation, polypropylene (PP) needs to be blended with low modulus materials to achieve toughening and softening. However, the compatibility between two or more resins can significantly affect the electrical properties of the composites.
