Zinc oxide arrester is a lightning protection device with superior protection performance, light weight, pollution resistance and stable performance. It mainly uses the good nonlinear volt-ampere characteristics of zinc oxide to make the current flowing through the arrester extremely small (microampere or milliampere level) at normal working voltage; when overvoltage acts, the resistance drops sharply, discharging the overvoltage energy to achieve the protection effect. The difference between this arrester and the traditional arrester is that it has no discharge gap, and uses the nonlinear characteristics of zinc oxide to play the role of current discharge and breaking.

Product Detail
ZheXi Electric Power Technology Co., Ltd., as a leading Zinc Oxide Arrester Manufacturer, offers a state‑of‑the‑art ZnO Gapless Surge Arrester engineered for superior lightning protection in electrical systems. This gap‑free design employs zinc oxide's nonlinear volt‑ampere characteristics to maintain microampere/milliampere currents under normal voltages and sharply reduce resistance during overvoltage events for rapid surge energy discharge. Unlike traditional arresters with discharge gaps, ZheXi's ZnO Gapless Surge Arrester enhances reliability and longevity by eliminating mechanical spark gaps subject to wear.

How To Choose, Install & Maintain
When choosing a Zinc Oxide Arrester Manufacturer's model (e.g., HY5WZ‑17/45, HY10W‑204/532), consider:
Rated Voltage (e.g., 17 kV, 204 kV) matching your system specifications.
Residual Voltage compatibility with protected equipment thresholds.
Nominal Discharge Current (5 kA, 10 kA) based on expected surge risks.
Creepage Distance (e.g., 50 mm/kV) for polluted or coastal environments.
Environmental Conditions, such as altitude, humidity, and pollution levels.
Follow IEC/local standards; mount vertically and secure to robust grounding systems.
Avoid mechanical stress and ensure proper torque on all connections.
Conduct Regular Inspections for cracks, corrosion, and pollutant buildup.
Monitor Leakage Current with diagnostic tools to detect early aging.
Perform Post‑Surge Checks: replace arresters after severe lightning events.
