Frequently Asked Questions

What is a metal oxide surge arrester (MOA)?

A Metal Oxide Surge Arrester uses zinc oxide blocks to limit overvoltages by conducting high current during surges and returning to high resistance afterward, protecting equipment from lightning and switching surges.

What’s the difference between gapped and gapless arresters?

Gapped arresters use spark gaps in series with MOV blocks, while gapless types rely solely on MOV material. Gapless designs offer faster response and better protection but require precise manufacturing.

Can you customize resistors for HVDC applications?

Yes, we manufacture damping, soft-start, and harmonic filter resistors for HVDC, SVG, and STATCOM systems up to ±800kV, with ceramic or metal construction based on thermal and electrical needs.

Do your products meet IEC standards?

Yes, our lightning surge arresters comply with IEC 60099-4, and all designs follow relevant IEC, GB, and ANSI standards depending on customer requirements.
