Product Features

This neutral‑point dedicated arrester provides effective over‑voltage protection for system neutral points against lightning and switching surges. Premium zinc‑oxide valve elements deliver rapid response and high discharge capacity. Gap‑type versions adopt self‑blowout gap structure to reduce discharge dispersion. The polymer composite housing has advantages of small size, light weight, anti‑pollution, explosion‑proof and shock‑resistant. Multiple structural options including gap‑free, series‑gap and parallel‑gap are available for neutral‑point application scenarios. It runs stably under standard service conditions: ambient temperature‑40℃~+40℃, altitude ≤2000 m, power frequency 50/60 Hz, seismic intensity ≤Ms7, maximum wind speed 35 m/s. Customized products are available for plateau, heavy‑pollution, corrosive‑gas and strong‑ultraviolet environments.
