Expert answers to common technical and commercial inquiries.
The core material is high-purity Zinc Oxide (ZnO) ceramics, which provide the non-linear resistance required to switch from an insulator to a conductor during a surge.
ZnO arresters have a much steeper non-linear V-I characteristic, meaning they can provide better protection levels with significantly lower leakage currents.
Polymer housings are lightweight, impact-resistant, and hydrophobic, which drastically reduces the risk of flashovers in polluted or humid environments.
We recommend annual visual inspections and leakage current measurements to ensure the ZnO elements are not degraded by repeated surge events.
Yes, our MOAs are designed for both AC and DC applications, providing excellent protection for PV systems and DC traction grids.
The energy class represents the amount of energy (kJ/kV) the arrester can absorb during a discharge without suffering permanent thermal damage.
