The Effects and Mechanisms of Thermal Oxygen Aging on Trap Characteristics and Electrical Performance of Functional Group‐Grafted Materials for HVDC Cable Insulation
In this study, N‐allylaniline (NA), a functional monomer possessing both deep trap‐inducing and antioxidant capabilities, was grafted onto cross‐linked polyethylene (XLPE) to prepare XLPE‐g‐NA. Both XLPE and XLPE‐g‐NA were subjected to thermo‐oxidative aging, and their physicochemical and electrical properties before...
