Product overview

FHJ lightning (arc) protection clamp is a device used to protect power lines from lightning damage.

Product Features

The FHJ lightning (arc) protection clamp consists of three parts: the main body, the arc starting plate, and the insulation cover, and is suitable for copper and aluminum overhead insulated wires. Its characteristics include:

High lightning resistance level: able to effectively respond to the impact of direct lightning or induced lightning, preventing lightning strikes, wire breakage, and tripping.

Easy installation: No need to peel, simple and fast installation.

Protection of wires: When lightning overvoltage exceeds a certain value, a short-circuit channel is formed through the arc plate and insulation cover, burning the power frequency arc, releasing overvoltage energy, and protecting the wires from burn.

Scope of application

FHJ type lightning (arc) protection clamp is suitable for copper and aluminum overhead insulated wires with a cross-sectional area of 50-240mm2. It is suitable for altitudes of 1000-3000 meters, ambient temperatures between -35 ℃ and 40 ℃, and maximum wind speeds ofAreas with speeds exceeding 35m/s.

Performance parameter

Lightning full wave impulse withstand voltage: 100KV

1-minute power frequency withstand voltage: 50KV

Power frequency arc current: 12.5KV
