Why Do You Need a Bird Flight Diverter?
A Bird Flight Diverter (BFD) is a device installed on overhead power line conductors to make them clearly visible to birds in flight — preventing fatal bird-wire collisions and protecting both wildlife and power infrastructure. India's Central Electricity Authority (CEA) has made BFD installation mandatory on all transmission lines near wildlife sanctuaries, Important Bird Areas (IBAs), and eco-sensitive zones.
Dynamic Bird Flight Diverters are wind-activated rotating devices that spin on the power line conductor, creating continuous motion-based visual alerts. The spinning motion makes them significantly more effective as bird deterrents compared to static markers — especially for large birds like eagles, vultures, cranes and the critically endangered Great Indian Bustard. CEA specifically recommends dynamic BFDs for eco-sensitive zones and Important Bird Areas (IBAs).
- 🌀Wind-Activated RotationSpins automatically with wind — no power, no battery needed. Motion creates the most effective visual alert for birds.
- 📋CEA Mandated for Eco-Sensitive ZonesCentral Electricity Authority recommends dynamic BFDs for all lines near wildlife sanctuaries, IBAs, and national parks.
- 🔧Hot-Line InstallationInstall on live energised lines — zero power shutdown required.
🌑 Non-LED — Glow in Dark Type Dynamic Diverters
Indolite's Non-LED Dynamic Bird Flight Diverters use special glow-in-the-dark phosphorescent material that charges during daylight and glows at night, providing passive 24-hour visibility without any battery or power source. These are the most cost-effective dynamic BFD solution for large-scale power line protection projects.
Entry-level dynamic bird diverter with wind-activated rotating blades and glow-in-dark coating. Ideal for standard 33kV–220kV transmission lines near bird habitat zones.
- Wind-activated rotation mechanism
- Glow-in-dark phosphorescent coating
- Day & passive night visibility
- CEA approved — all voltage levels

💡 LED Type — Dual Visibility (6 LEDs Each Face)
Indolite's LED Bird Flight Diverters are the most advanced bird protection devices available in India. Each unit features 6 LEDs per face providing active illumination — making the diverter clearly visible from hundreds of metres away at night. These are the recommended solution for the highest-risk transmission corridors, including lines passing through Great Indian Bustard (GIB) habitats, flamingo flyways, and crane migration routes.
Solar-charged LED dynamic bird diverter with 6 high-intensity LEDs per face. Provides active night illumination and wind-activated daytime rotation — dual visibility 24×7.
- 6 high-intensity LEDs per face
- Solar-powered — no wiring needed

- Forest & Wildlife Board accepted
Static Bird Flight Diverters are fixed, passive overhead power line markers with no moving parts. They rely on high-visibility orange and black colouring combined with UV-reflective coatings to make overhead conductors clearly visible to birds. With zero maintenance requirements and 10–15 year outdoor lifespan, static BFDs are the most cost-effective solution for large-scale line-marking projects in open terrain and high-wind corridors.
India's most popular helical bird diverter — the classic yellow spiral that wraps 360° around the conductor for all-direction visibility. Zero moving parts, zero maintenance.
- 360° wrap-around helical design
- Visible from all flight directions
- UV-stabilised yellow polymer
- Zero moving parts — zero maintenance
- Quick clip-on — no wire splicing
- CEA approved · 10–15 year lifespan
Standard CEA-approved flat static bird marker in high-visibility orange & black. The most widely deployed overhead power line marker across India's transmission network.
- CEA standard orange & black colouring
- UV-reflective coating — day & night
- Lightest & most cost-effective BFD
- Ideal for high-wind open terrain
- Clip-on hot-line installation
- 10–15 year outdoor lifespan
