YUANKY 30/80 type for neutral point YH series polymeric housed arresters

Yuanky YH series polymeric housed arresters for neutral point are key insulation‑coordination devices for power‑system equipment. It restrains lightning and internal operating over‑voltage for neutral‑point of AC power systems up to 220kV. Adopting zinc‑oxide‑based multi‑metal‑oxide resistor chips as core components, it features excellent non‑linear volt‑ampere characteristics, fast response and large discharge capacity. Composite polymer housing realizes compact size and maintenance‑free performance and complies with IEC and relevant national standards.

Product Description

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.
