Protecting bird populations and ensuring grid reliability

High-voltage transmission lines can pose significant risks to bird populations, while disruptions caused by birds can also threaten the reliability of the electrical grid. Common challenges include:

  • Avian power line collisions: Birds fatally striking, or colliding with, power lines
  • Nest-related issues: Increased bird activity and nests can bridge energized areas, leading to power outages, bird electrocutions, and even fires
  • Streamer-caused outages: Birds perching on structures above insulators can cause outages and electrocutions due to defecation (also known as streamers)

At Power Line Sentry, we offer a comprehensive range of solutions, from industry-leading nesting and perching diverters to the most reflective and effective avian flight diverters available. Our products are designed to prevent wildlife-related outages and protect both birds and the electrical grid.

Hawk eyeTM bird flight diverters

Bird flight diverter: Mirrored fluorescent yellow for light reflection. 24-hour glow. A-frame for visibility. Rubber hose protects wire. No mechanical parts. Up to 500 kV. Easy hot stick or robot/drone install.

Raptor guardTM nesting diverters

Nesting diverter: Proven to deflect sticks and deter nesting activity. Diverter extends to perfectly fit variety of structure types and lengths.

Raptor guardTM spike perching diverters 

Perching diverter: Deters birds from perching in dangerous areas. Blunt fiberglass rods are built to withstand extreme conditions. Fast, easy install.
 

All Power Line Sentry (a Sicame Group's subsidiary) nest diverters feature a unique inverted “V” shape that is effective at shedding sticks that birds drop or place in an attempt to build nests, making it especially appropriate for osprey and eagles.

Nesting on power structures is a critical issue. The nests can cause phase-to-ground power outages, fires, and avian electrocutions due to increased bird activity around the nest – and with populations of avian species that nest on power structures (osprey, raven, etc.) rapidly recovering/increasing, nesting activity is becoming a serious problem.

Power Line Sentry nesting diverters effectively deter nesting abilities and are proven to work even when past nesting activity has occurred.

Power Line SentryTM Raptor guardTM  perching deterrents

Raptor guardTM spike and pole top cap perching deterrents eliminate surface area available for birds to perch, therefore reducing potential connection of energized areas, including connections made from bird streamers.
