Bird Flight Diverter
BIRD-FLIGHT Diverter is an effective warning solution for reducing bird collisions with powerlines. More than one device is installed on a powerline to improve visibility.
Transmission and powerline companies use several types of bird flight diverters. This specific model is a helical bird flight diverter, also known as an Optical Fiber bird flight diverter. It comes in two types: a single-head bird diverter and a double-head bird diverter, providing different options to suit specific installation needs.
This product functions as a diverter. It’s brightly colored to divert birds like waterfowls and raptors from distribution-level powerlines.
BIRD-FLIGHT Diverter minimizes and/or eliminates collisions. It is usually installed on the sections of lines crossing. The bright yellow exterior of the bird diverter illuminates a transmission line. As a result, birds perceive the lines as something to avoid during their flight.
The main accessory that is used with BIRD-FLIGHT Diverter is a hot stick. Similarly, the installation of the diverter can be done by hand.
The helical coil has a larger end that slips easily over a transmission line. Then, the coil is rotated until the line is completely inside all the helices. The other end of the diverter has a securing helix that wraps around the line.
Main Features
- High-impact PVC construction
- Lightweight and easy to install by hot stick or hand
- Brightly yellow colored for improved visibility
- Meets the required flammability requirements
- Minimal wind resistance

Frequency Asked Questions
What is a Bird Flight Diverter?
Lightweight and light-reflecting, bird flight diverters keep birds from colliding with electrical conductors.
Key Functions of Bird Flight Diverters
Transmission and distribution industry uses bird diverters to make the powerlines visible to birds. The industry achieves this by making the surfaces of the diverters reflective and glowing. It is also with the help of bird flight diverters the industry is able to improve avian protection. Endangered migratory birds can avoid electrocution during their long flights.
How a Bird Flight Diverter Works?
A bird flight diverter must be attached to an electrical conductor or powerline. Contractors usually install them in strategic positions to make the entire line visible to the birds. This visual aid encourages them to change their flight path to avoid colliding with the lines ahead.
What are the Applications of Bird Flight Diverters?
These light-reflecting inventions are primarily used in transmission and distribution powerlines. They make the powerlines visible and easy to evade.
Main Types of Bird Flight Diverters
Bird flight diverters exist in different styles and shapes. However, the main types seen along most electrical conductors are helical and dynamic diverters.
Bird flight diverters with a helical structure have the simplest design. They appear like a reflective coiled wire on a powerline. Besides, most helical diverters have a yellow glowing surface.
Diverters with a dynamic structure have more than one component. They have a clamp for hanging on an electrical conductor, a warning disc (the key part of the bird flight diverter), and connectors for attaching the disc to the clamp.
What are the Key Features of Bird Flight Diverters?
A bird flight diverter can have a helical or dynamic design, depending on the type. These warning devices have a weather-resistant construction. They can withstand extreme temperatures, snow, wind, and rain once installed. What makes them so effective is their reflective surfaces, which glow to improve visibility. In addition, the lightweight material is not a fire hazard.
