Minimizing Collision Risks With Bird Flight Diverter

During multiple research done worldwide on avian collisions, well elaborates that they have the potential to stay away from powerlines only if they are able to identify the said obstacles pretty much early.

Many research also specifies that destruction created by collisions can be reduced by more than half and, in some cases, by as much as 80% only if the lines are well marked by marking devices.

Adding further on the said topic we will be adding very effecting questions like,

What do we know about the line marking devices? Different Types of Available Devices in the market.

Their effectiveness, and considerations /durability with time.

Avian collisions mainly take place with the smallest diameter wire, which is very well available like the shield wire located above the phase conductors on powerlines or the phase conductor and neutral wire on distribution lines.

Generally, there are three types of line marking devices such as:-

• Aerial Marker Spheres
• Spirals
• Suspended Devices (swinging, flapping, and fixed)

Introducing wires with large diameter though not a marking device can also help in improving the powerlines visibility for avian species. Once theses used in combination with line marking devices can give outstanding results in reducing mortality by collisions and electrocutions.

Companies have updated their old devices like aerial marker spheres, spirals, and suspended devices with time in case of shapes, colour patterns and types of attachments as well as ultraviolet resistance. As these factors highly refine durability and visibility.

Around the globe, top Powerline companies highly suggest suspended line marking devices in comparison to small-diameter spiral specifically because of their swinging or flapping motion, which makes them more noticeable and effective towards avian species. These marking devices are well available in multiple shapes and colours. line marking devices available worldwide

NAME	DESCRIPTION
Aerial Marker Spheres or Aviation Balls	Large, colored spheres that Spheres or attach to wires
Spiral Vibration Damper (SVD)	Extruded plastic(pvc)spiral device that fits over the shield wire and distribution conductor
Bird-Flight Diverter (BFD)	Spiral device made from high impact PVC that attaches at one end to the shield wire or distribution conductor and increases in diameter at the other end.
Swan-Flight™Diverter (SFD)	Similar to the BFD, but this device attaches at both ends with the larger diameter spirals in the centre.
General Designs	Swinging and fixed devices Design plastic flapper of various shapes and colors with reflective and glowing surfaces; connected to a clamp that attaches to the power line
Fire Fly	Swinging and fixed models; rectangular devices with reflective and glowing surfaces; connected to a clamp that attaches to the power line
BirdMark	Swinging perforated disk has a reflective center and spins and flutters, it also glows; connected to a clamp that attaches to the power line; perforations allow device more wear resistance in high wind locations

Choosing the right line marking device for your projects is based on the following scenarios:-Product Availability, Durability ,Cost, Ease Of Product Installation, Spacing And Positioning , Weather Conditions ,Environment Condition and above all Compliance And Legal Issues.
