Polypropylene-based nanodielectrics for HVDC cables

, 2021
Due to the limited recyclability and operating temperature of the cross-linked polyethylene (XLPE) insulation for high voltage direct current (HVDC) cables, renewable next-generation insulation materials have drawn great attention during recent years, especially polypropylene-based nanodielectrics. The filler-matrix interphase within nanodielectrics is
