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

Development of Cable Accessories with SiR Insulation for 320kV HVDC Cables [PDF]
E3S Web of Conferences, 2019 HVDC cable accessories with environment-friendly insulating material and flexible compatibility other than ethylene propylene diene monomer (EPDM) are demanded in the global market. In this paper, the authors present their newly developed silicone rubber (SiR) insulated cable joints and terminations as a potential answer to that call. Simulation models
