Valve arrester, containing varistors connected in series to form a working resistor placed in a hollow insulator, characterized in that the axes of revolution (Ow) of the varistor units (2, 3) lie in at least one plane (P) passing through the axis of symmetry (O) of the arrester, and the groups of varistors (2, 3) are in contact, in alternating fashion, with the internal surface of the hollow insulator (1) in such a way that the lines of contact overlap with the lines, where the plane (P) intersects the internal surface of the hollow insulator (1).<IMAGE>
