Describe Display

The FHY5C-10C puncture-type air-gap surge arrester combines a precision-engineered zinc oxide varistor with an external air-gap spark path to deliver reliable overvoltage protection in 10 kV distribution networks. Its innovative puncture mounting allows direct installation on live lines without specialized tools, speeding deployment and reducing labor costs.

Designed for harsh outdoor environments, the arrester’s sealed, weather-resistant housing withstands moisture, UV exposure, and pollution. The external arc-gap enhances contamination tolerance, while the MO varistor core offers stable clamping characteristics and long-term durability—ensuring continuous protection for transformers, lines, and other critical assets.
