Bird Guard - Perch Deterrent for Power Transmission Lines
Protect Birds. Protect Power Infrastructure. Protect India.
Indolite Devices Pvt. Ltd. is India's trusted manufacturer of Perch Deterrents (Bird Guards) and Solutions for Mitigating Bird Electrocution for high-voltage transmission lines, substations, and power grid infrastructure.
Large birds like peacocks, vultures, eagles, kites, and storks often perch on transmission tower cross-arms. During take-off, their wide wingspans can contact live conductors-while their feet are grounded on tower, causing fatal electrocution, power outages, power tripping and grid instability.
Indolite™ Perch Deterrent is the most effective and economical way to prevent birds from perching on transmission towers, insulators, and cross arms. This innovative solution has proven to be a boon in preventing tripping and breakdowns caused by birds.
Indolite™ Perch Deterrent is a world-class product designed to tackle the menace of birds without harming them. Perching of birds on transmission lines and towers can cause significant issues, particularly the electrocution of large birds such as peacocks, raptors, kites, and the Great Indian Bustard.
This device is specifically engineered to deter birds, especially large species, from perching on power transmission towers. It is non-fatal and humane, ensuring that birds are dissuaded from sitting on transmission lines and towers without being harmed.
The height and inaccessibility of transmission towers make them ideal perching grounds for birds. These high vantage points provide clear views for birds and also create protected zones, away from the reach of predators.
Indolite™ Perch Deterrent is designed to prevent birds from perching in unwanted places. This product is non-fatal and humane, ensuring that birds are deterred without harm.
The investment in Indolite™ Perch Deterrent pays off within a few months, and the product continues to deliver results for years. We are confident that once you install this device, you will find it invaluable.
Designed and tested extensively for installation on crossarms of up to 765kV transmission towers. Non Conductive construction of Indolite™ Perch Deterrent offers safe electrical clearances to live conductors. It also prevents birds from roosting on critical components like the crossarm, tower top and insulator strings, improving infrastructure reliability and bird safety.
Indolite™ Perch Deterrent is manufactured entirely from special-grade engineering plastic. It contains no metallic components anywhere in its construction — including the base, spikes/prongs, and connecting links — ensuring it is completely non-conductive and safe for use in close proximity to live high-voltage conductors.
Installation is tool-minimal and does not require drilling, welding, or modification to the tower structure. The device is fitted using tailor-made non-metallic clamps designed to grip the crossarm/tower member securely.
| Step | Description |
|---|---|
| 1 | Identify perching zones on crossarm / tower peak / cross-member requiring protection. |
| 2 | Position the Perch Deterrent unit(s) along the identified member using the modular chain-link feature for continuous coverage. |
| 3 | Secure using the supplied non-metallic clamp — hand-tightened, no special tools or line shutdown required for most tower positions. |
| 4 | Link additional units end-to-end as needed to cover the full length of the crossarm. |
| 5 | Visually inspect fitment and clearance from live conductors before commissioning. |
