Frequently Asked Questions

What is a metal oxide surge arrester?

A metal oxide surge arrester (MOSA) uses zinc oxide blocks to limit overvoltage on equipment by diverting surge current. It provides excellent protection against lightning and switching surges.

What voltage ranges do you offer?

We manufacture arresters from 0.22kV up to 500kV, covering low, medium, and high-voltage applications in substations, transmission lines, and industrial systems.

Do you offer custom designs?

Yes, our internal R&D team supports OEM and ODM projects. We can customize voltage ratings, housing materials, mounting configurations, and more.

What certifications do your products have?

Our products comply with IEC60099-4, RoHS, and other international standards. We maintain a strict quality control system and in-house testing laboratory.
