The Bird Flight Diverter enhances the visibility of overhead power lines and guyed structures to birds, reducing collision risk in areas with high avian activity. Its patented shape maximizes contrast in low-light conditions through 360-degree visibility, utilizing highly reflective and glow-in-the-dark bands. Research shows that contrast is critical for alerting birds to hard-to-see objects, and the structure ensures minimal wind resistance while providing long-distance visibility.
Constructed from rigid, high-impact Polyvinyl Chloride (PVC) with thicknesses of 0.375 inches and 0.5 inches, the diverter resists moisture, corrosion, and chemicals. Alternative versions use corrosion-resistant aluminum alloy for elevated temperatures up to 250°C. Materials receive Ultraviolet (UV) protection to maintain integrity under prolonged exposure. The lightweight construction features a positive grip mechanism that prevents movement along the span.
Applications span low-, medium-, and high-voltage power lines, including phase conductors, shield wires, and Optical Ground Wire (OPGW) cables, particularly in regions with avian migration corridors or endangered species habitats. Independent testing by organizations such as the Electric Power Research Institute (EPRI) has validated effectiveness, with the U.S. Fish and Wildlife Service issuing recommendations for installation.
Installation methods include manual application by hand or hot stick, and robotic systems enabling rapid placement. Recommended spacing intervals of 15 feet optimize effectiveness, with the design allowing quick, secure attachment and minimal maintenance throughout its operational life.
Trust RaxPower, Expert Bird Flight Diverter Wholesaler
RaxPower, the leading manufacturer of bird flight diverters and LED bird flight diverters for powerlines, provides high-quality solutions to reduce bird collisions on transmission lines. Our innovative diverters, manufactured in China, adhere to industry standards and have passed SGS tests, ensuring compliance and reliability. With over 21 years of experience, we offer helical and dynamic bird flight diverters designed for maximum visibility and safety.
The BIRD-FLIGHT Diverter is engineered to make overhead lines and guyed structures visible to birds, providing an economical means of reducing hazards. The bright yellow exterior illuminates the transmission line, so birds perceive it as something to avoid during flight. This cause-and-effect design effectively prevents collisions.
Our Bird Flight Diverter includes several key features:
- Manufactured from high-impact PVC with UV protection for durability.
- Lightweight and easily installed by hand or with a hot stick.
- Weather-resistant construction withstands extreme conditions.
- Reflective surfaces enhance visibility in low-light environments.
For optimal performance, install the diverters at 15-foot intervals on power lines.

Frequently Asked Questions (FAQS)
A bird flight diverter is a device that makes overhead power lines and guyed structures visible to birds, reducing collision hazards. It works by providing maximum contrast through brightly colored surfaces, reflective materials, and glow-in-the-dark bands in some models, alerting birds to hard-to-see objects and allowing them to change flight path, especially in low-light conditions.
Bird flight diverters prevent bird mortalities from collisions and electrocutions, which cause power outages and equipment damage. They help utilities avoid fines, comply with regulations, protect endangered species, and contribute to wildlife conservation and grid reliability.
Bird flight diverters are manufactured from durable materials such as rigid high-impact PVC, corrosion-resistant aluminum alloy, or galvanized steel. These materials offer excellent chemical resistance, tensile strength, UV protection, and retain good physical characteristics in extreme temperatures. They meet UL 94 V-0 flammability requirements and are designed for long service life without deterioration.
Bird flight diverters can be installed manually by hand or using a hot stick, and robotically with aerial systems for faster, accurate sequential placement. The recommended spacing is typically 15-foot intervals, though some research suggests 5 meters (16 feet) for optimal effectiveness in reducing collision probability.
