Product Introduction

Surge arresters quickly clamp excessive voltage and divert surge current to the ground, ensuring the safe and stable operation of the power distribution network. With their lightweight, durable, and weather-resistant design, they are widely used in power grids, industrial facilities, and infrastructure projects around the world.

Application areas

3kV-35kV power distribution lines
Surge protection for distribution transformers, switchgear and power cabinets
Overhead power line, cable termination and capacitor bank protection
Industrial plants, commercial buildings, and renewable energy (solar/wind) power plants
Power supply systems for railways, highways, and airports

Environmental adaptability

Coastal areas: Resistant to salt spray, high humidity, and marine corrosion.
Industrial areas: Resistant to dust, chemical fumes, and acid rain.
High altitude areas: Stable performance at 4500 meters
Extreme temperatures: -40℃ to +85℃ for normal operation
Outdoor environment: Resistance to wind, rain, ultraviolet radiation, and ozone aging.
