Claims

[Scope of utility model registration request]

(1) Multiple nonlinear resistor elements are arranged in a zigzag pattern. The inner elements formed by stacking each other via the edge members are housed inside the container to form a surge arrester unit, and the plurality of surge arrester units are connected in series and arranged upright, and the uppermost one is arranged vertically. A high voltage is applied to the top of the lightning arrester unit, the lower end of the bottom lightning arrester unit is grounded, the dielectric constant of the insulating member inside the top lightning arrester unit is selected to be the largest, and the inside of the lightning arrester units to be connected in sequence is A lightning arrester characterized in that the dielectric constant of the insulating member is selected to be gradually lowered.

(2) The lightning arrester according to claim 1 of the utility model registration, in which the dielectric constant of the insulating member inside the uppermost lightning arrester unit is selected to be at least 6.
