Adding voltage stabilizer is a promising method to develop high-performance polymer insulating materials for HVDC cables. In this chapter, voltage stabilizers are classified into three categories according to the different mechanisms of inhibiting electrical tree initiation, namely inhibiting partial discharge, capturing high-energy electrons and inhibiting macromolecular degradation. The hot research topics and relevant research progresses of voltage stabilizer as well as the influences of voltage stabilizers on the DC insulation performances of polymer insulating materials are summarized. The satisfactory progress has been made by relevant researches on alkylated voltage stabilizer, quantum chemical calculation and the combined use of voltage stabilizer and nanoparticles, which are the hot research topics of voltage stabilizer recently. The voltage stabilizers exhibit excellent effects on improving the DC breakdown strength and DC electrical tree resistance of the polymeric insulations including polyethylene and polypropylene. The proper use of voltage stabilizers also has positive effects on inhibiting space charge accumulation in polymeric insulation. However, the mechanism of voltage stabilizers’ effects on the charge transport behaviors in polymeric insulation and how to use voltage stabilizer to regulate the charge transport need further study.
