Problem: Bird Collision with OHE Transmission Lines
Most bird strikes occur during low-light conditions — early morning, dusk, fog, and night time.
Traditional bird markers work only in daylight. Once sunlight fades, they cannot be seen.
However, many birds migrate and feed at night. Waterfowl, cranes, and many migratory species are highly active during these hours.
Without night time visibility, power lines become hidden hazards — leading to bird deaths and infrastructure damage. The Great Indian Bustard generally feeds at dawn and dusk. Due to low frontal vision of GIB, low-light conditions enhance its vulnerability to accidents.
The Advanced Solution: Glow-in-Dark Static Bird Flight Diverter
The IndoDivert™ Static Bird Flight Diverter uses advanced photoluminescent technology to provide visibility even in low light conditions.
During daylight, the BFD absorbs UV energy from sunlight. At night, it automatically emits stored light — glowing for many hours without electricity or batteries. Whole body of Indolite Bird Flight Diverter glows in dark, thus increases visibility of power lines even in low light conditions.
This mitigates chances of bird collision — day and night.
Field performance shows up to 60% reduction in bird collisions, with even greater improvement during low-light hours.
How It Works
Daytime Protection
The 150mm "A" shape or "TENT" shaped reflective stripes provide strong contrast and high visibility during daylight.
Secure Anti-Skid Mounting
The PU/ rubber inner lining grips firmly, preventing rotation and maintaining optimal positioning for maximum bird visibility.

Frequently Asked Questions – Glow-in-Dark Static Bird Flight Diverter
Q1
What is the Glow-in-Dark Static Bird Flight Diverter and how does it prevent bird collisions on OHE transmission lines?
+
The IndoDivert™ Glow-in-Dark Static Bird Flight Diverter is a high-visibility, non-conductive bird diverter designed for OHE transmission lines and overhead power conductors. It uses advanced photoluminescent technology to absorb UV sunlight during the day and emit stored light at night, making power lines visible in low-light conditions such as dawn, dusk, fog, and nighttime. This significantly reduces bird collisions with transmission infrastructure.
Q2
How effective is the Glow-in-Dark Bird Flight Diverter in reducing bird strikes during low-light conditions?
+
Field performance studies indicate up to 60% reduction in bird collisions, with even higher effectiveness during early morning, dusk, fog, and night-time conditions. Unlike traditional bird markers that only work in daylight, this static bird diverter continues glowing for hours without electricity or batteries, ensuring 24x7 bird safety.
Q3
Why are traditional bird flight diverters ineffective at night?
+
Traditional bird diverters rely only on daylight reflection. Once sunlight fades, they become nearly invisible. Many species such as migratory birds, waterfowl, cranes, and the Great Indian Bustard are active during dawn and dusk. The Glow-in-Dark Static BFD solves this problem by emitting stored light in darkness, increasing line visibility when birds are most vulnerable.
Q4
How does the photoluminescent technology work in this bird diverter?
+
The entire body of the Static Bird Flight Diverter is made from photoluminescent UV-stabilized engineering polymer. During daylight, it absorbs ultraviolet energy from sunlight. At night, it automatically releases the stored energy as visible glow, ensuring enhanced power line visibility without requiring batteries, wiring, or external power supply.
Q5
Is the Glow-in-Dark Static Bird Flight Diverter safe for high-voltage transmission lines?
+
Yes. The diverter is non-conductive and corona-free up to 500 kV, making it completely safe for EHV, HV, and OHE transmission lines. It contains no metal or moving parts, ensuring long-term durability and electrical safety.
Q6
What makes the mounting system secure and anti-rotational?
+
The diverter features an anti-skid PU / rubber inner lining that firmly grips the conductor. This prevents rotation due to wind or vibration and ensures the “A” frame or tent-shaped reflective surface always remains properly aligned for maximum bird visibility.
Q7
Which conductor sizes are compatible with the Static Bird Flight Diverter?
+
The Glow-in-Dark Static Bird Flight Diverter is available for OPGW and conductors ranging from Ø 7mm to Ø 38mm. It is suitable for transmission lines, railway OHE lines, river crossings, wetlands, migration corridors, and wildlife-sensitive zones.
