FIELD: electrical engineering. SUBSTANCE: arrester has casing, formed by metal cylindrical body and insulator in the shape of hollow truncated cone, and two electrodes. Electrode positioned on internal surface of one of body faces has working surface diameter at least one and a half times as large as working surface diameter of electrode located on conical insulator. EFFECT: more effective construction. 1 dwg
