FIELD: electrical engineering.
SUBSTANCE: invention relates to a lightning protector of electrical equipment elements or a transmission line comprising an insulating body, made from a dielectric, and five or more electrodes mechanically coupled to the insulating body and arranged to produce, under the influence of lightning overvoltage, electric discharge between adjacent electrodes (2), wherein the electrodes are located inside insulating body (1) and separated from its surface by an insulation layer. Neighboring electrodes protrude into discharge chambers (3), having exits (4) on the surface of the insulating body. At least one discharge chamber has two or more outlets to the surface of the insulating body.
EFFECT: invention provides the following: arc of the discharge is extinguished after passing a lightning overvoltage pulse before the passage of the accompanying current having an industrial frequency through zero mainly immediately after a lightning surge.
