Improving　the　electrical　treeing　resistance　of　polymer　is　of　great　significance　for　insulation　reliability.　To　achieve　this,　a　solution-based　method　is　employed　to　introduce　a　voltage　stabilizer　with　high　electron　affinity　into　the　silicone　rubber　(SiR).　Experimental　findings　demonstrate　the　voltage　stabilizer＇s　ability　to　improve　the　tree　initiation　voltage　and　provide　evidence　of　their　migration　within　the　SiR.　Additionally,　by　combining　a　finite　element　method,　it　has　been　confirmed　that　voltage　stabilizers　can　migrate　through　dielectrophoresis　in　non-uniform　electric　fields　and　adaptively　reposition　themselves　in　response　to　changes　in　electric　field　distribution　during　the　growth　of　the　electrical　tree.　©　2023　Author(s).
