The accumulation of space charge is easy to cause the internal electric field distortion of cross-linked polyethylene insulation, resulting in insulation ageing and even failure. Nano-doping or modification can inhibit the accumulation of space charge, so it has received widespread attention. In this paper, the space charge properties and electrical conductivity properties of cross-linked polyethylene composite doped by silica and magnesium oxide nano filler were measured, and the action mechanism of nanofillers was analyzed combined with the theoretical band gap model. The results show that the MgO-doped cross-linked polyethylene composites have higher dielectric constant, lower space charge accumulation, and smaller electrical conductivity compared to silica-doped cross-linked polyethylene composites.
