FIELD: electricity.
SUBSTANCE: in the method to manufacture an oxide-zinc varistor including preparation of an initial composition on the basis of zinc oxide, shaping of a varistor stock by pressing, heating of the stock and its subsequent annealing, according to the invention, the stock is shaped by means of pressing of the initial composition, and the stock is heated in the electromagnetic field of ultrahigh frequency as the stock is placed in the mould made from a material with high value of tangent of the dielectric losses angle.
EFFECT: simplification and reduction of duration of the method to manufacture an oxide-zinc varistor.
