A Zinc Oxide Surge Arrester is a protective device used in electrical power systems to prevent damage caused by high voltage surges, such as lightning strikes or switching events. It contains zinc oxide varistors (MOV) that quickly absorb and divert surge energy to the ground, protecting transformers, cables, and other equipment from electrical faults. Known for fast response, high reliability, and low maintenance, ZnO surge arresters are widely used in medium and high voltage networks
Our ZnO surge arresters are available with voltage ratings from 3kV up to 220kV, covering medium and high voltage power systems to meet various application needs.
We provide surge arresters with both polymer and porcelain housings. Polymer housings offer excellent UV resistance and lightweight advantages, while porcelain housings provide high mechanical strength and durability.
Yes, all our ZnO surge arresters are tested and certified according to IEC 60099-4 standards, ensuring reliable performance and safety.
Yes, our surge arresters are designed for both indoor and outdoor use, with weatherproof housings suitable for harsh environmental conditions.
We offer optional accessories including disconnectors, surge counters, and remote monitoring systems to enhance protection and facilitate maintenance.
MOV (Metal Oxide Varistor) technology allows the arrester to respond quickly to overvoltage events by absorbing surge energy without spark gaps, resulting in faster, more reliable protection and longer service life.
Yes, we provide OEM and customized solutions based on your specific voltage, size, and accessory requirements.
They are widely used in substations, transformers, overhead transmission lines, and switchgear to protect electrical infrastructure from surges.
Maintenance is minimal; however, using optional remote monitoring and surge counters helps track arrester status and plan timely replacements to ensure system reliability.
