sf6 insulated switchgear Charging for 121kv

Aug 08, 2020The use of materials promoting charge concentration is thus avoided in gas insulated systems. Alumina-filled epoxy matrix is a common insulating material for GIS-related applications. The filler alumina offers good resistance to decomposed SF6 products like hydrofluoric acid (HF) as compared to silica or felspar (common fillers used with epoxy).
