Avian species have always been a major point of concern when it comes to bird collisions and electrocutions caused by power lines. Across the world, researchers, conservationists, and power utility experts have developed modern and advanced bird protection devices to significantly reduce bird mortalities.
Among these innovations, line marking devices play a crucial role. Popular solutions include Bird Flappers, Bird Deflectors, Bird Spirals, Bird Reflectors, Crossed Bands, Bird Flight Diverters, and LED Bird Flight Diverters. Out of all these technologies, Bird Diverters and Bird Flight Diverters are considered the most effective and widely used solutions in the global market.
We all have a curiosity to know what exactly a Bird Diverter is and how it looks like? Many people are curious to know what exactly a Bird Diverter is and how it looks.
If you have ever been on a jungle safari, camping trip, or visited open natural landscapes, you may have noticed power transmission towers and overhead power lines stretching across vast areas. On closer observation, you might have seen unusual objects attached to these lines.
These objects may appear as round discs, balls, spirals, spheres, or rotating devices, often available in bright colors and sometimes equipped with illuminating or reflective features. These devices can be fixed or rotating, depending on their design and application.
During your jungle safari, camping tours or visiting places where you experience huge naturals lawns and surroundings, sighting powerlines tower and other power distribution infrastructures are very common. You must have noticed strange kind of objects both Fixed and rotating like round disks, balls, spheres (with the illuminating feature) etc of different colors and sizes hanging on powerlines are known as bird diverters.

Avian species migration leads to collision specifically because of their poor frontal vision. Installing Bird flight diverters on powerlines will increase the visibility among avian species and also acts as rescuer. Often you can have a glimpse of these devices while passing through deep valley areas, near major freeway crossings and huge farming fields.

This PDF provides complete technical details of ACSR (Aluminium Conductor Steel Reinforced) conductors used in overhead power transmission and distribution lines. It includes all essential engineering data such as conductor type, diameter, stranding, mechanical strength, aluminium and steel area, and electrical resistance.
The document lists multiple conductor categories in both Metric and British sizes, giving engineers and buyers accurate specifications required for designing and selecting the right conductor. Each conductor’s outer diameter, wire size, weight per kilometre, and rated strength are clearly shown to support safe and efficient installation of transmission lines.
This PDF is especially useful for utilities, EPC contractors, electrical engineers, transmission line designers, and procurement teams who need verified and reliable technical information for ACSR conductors.
The IndoDivert WMSv2 is Indolite's advanced-generation dynamic bird flight diverter engineered for the highest-priority bird protection zones in India. As a premium No-LED bird diverter, the WMSv2 features a dual-bearing rotation mechanism and next-generation phosphorescent glow-in-dark coating — delivering superior performance in critical ecosystems where standard single-bearing models may not suffice.
The WMSv2 is widely recognised as the best bird flight diverter in the non-LED category for Important Bird Areas (IBAs), Wildlife Sanctuaries, and critical bird flight diverter in transmission line corridors where the Great Indian Bustard (GIB), flamingos, cranes, and migratory waterfowl are present.
The WMSv2 illustrates advanced how bird diverter works engineering through a multi-layer protection system:
Advanced dual-bearing dynamic BFD for IBAs, wildlife sanctuaries and critical transmission corridors across India.

The Bird Flight Diverter WMSv1 is the most advanced Non-LED dynamic bird diverter for overhead power lines. It combines 360° aerodynamic swivel, dual-colour 3M retro-reflective power line marker stickers, and a 12-hour glow-in-dark surface — delivering complete 24/7 power line protection as the world's best wildlife protection device.
A bird diverter is a wildlife protection device mounted on overhead conductors to alert birds in flight and prevent fatal collisions. The WMSv1 is the most complete bird diverter — combining motion, reflection, and glow-in-dark for 24/7 power line protection.
Prevents bird collisions on overhead power lines through movement, reflection, and glow — the most complete bird diverter available.
Certified wildlife protection device trusted by utilities in migratory corridors, wetlands, and protected wildlife zones worldwide.
3M retro-reflective orange and yellow stickers deliver high-visibility power line marking in all daylight and low-light conditions.
Six engineering advantages that make the Bird Flight Diverter WMSv1 the most effective Non-LED bird deterrent and power line protection device available.
Minimum 7,500 sq mm glow-in-dark surface — up to 12 continuous hours afterglow after charging in daylight. Zero batteries. Zero electricity.
Aerodynamic wings + precision swivel rotate fully in wind. Alerts birds from far greater distances than any static bird deterrent or fixed power line marker.
DYNAMIC TYPEMin. 3,500 sq mm per face of certified 3M orange and yellow stickers. Dual-colour faces maximise daytime power line marker visibility in fog and low-angle sun.
3M CERTIFIEDFits ACSR, OPGW, earth wires — all outer diameters. Over 95% contact area. 500 N tensile and 250 N slip strength. No line outage needed.
ALL CONDUCTORSAll hardware except metallic clamp parts is non-conductive. Zero visual corona up to 220kV. Passes RIV per IEC 61284 Cl.14.6. Safe for HV and EHV lines.
220KV RATEDOperates at -15°C to +85°C. Tested to MIL-STD 810F for solar radiation, sand and dust, salt fog, and humidity. Zero maintenance for decades.
MIL-STD 810FMost bird diverters only work in daylight. The WMSv1 is different — its glow-in-dark surface charges automatically during the day and emits light for up to 12 continuous hours after sunset.
This makes the WMSv1 the only Non-LED bird deterrent that delivers true 24/7 wildlife protection device performance — covering dusk, dawn, moonless nights, fog, and overcast conditions when bird collision risk is highest.
