Disclosed are a zinc oxide surge arrester valve having a lead-free highly-insulating ceramic coating, and a preparation method therefor. The zinc oxide surge arrester valve having a lead-free highly-insulating ceramic coating comprises a surge arrester valve body 1, the sides whereof are covered with a lead-free highly-insulating ceramic coating layer 2, and the top and bottom whereof are coated with an aluminum layer 3; the highly-insulating ceramic coating is prepared from the following components in the following mass ratio ranges: ZnO: 86-95%，Bi203: 1.0-3.0%, Co3O4: 0.5-1.5%, Mn3O4: 0.2-1.0%, Sb2O3: 3.0-9.0%, NiO: 0.2-1.0%, SiO2: 1.0-3.0%, and a PVA solution, and agate grinding balls. As the present formulation comprises no lead, no toxic substances are produced during the preparation process; the absence of lead is socially and environmentally-friendly, is environmentally beneficial, and is in step with current global trends for sustainable development.
