Technicians who have spent many years maintaining power lines have a love-hate relationship with birds. They love them because, while patrolling the lines in the middle of nowhere, hearing a few bird calls makes them feel less lonely. They “hate” them because these little creatures are so good at picking places to nest. To birds, those steel towers standing dozens of meters high are simply the perfect spots—high up, with great views, and structurally stable. However, their droppings, along with the wires and twigs they bring back in their beaks, can fall onto live equipment at any moment, causing short circuits, circuit breakers to trip, and flashover.
In the past, when faced with this situation, the most direct solution was to remove the bird nests. But even if we removed them today, the birds would build new ones tomorrow—a never-ending cycle, much like a game of cat-and-mouse. More importantly, people are increasingly realizing that the issue between power grids and birds isn’t a matter of who is right or wrong, but rather whether we can find a solution that benefits both. In recent years, the power industry’s approach to bird control has quietly shifted. People have realized that while power poles are large, not every spot on them is dangerous. Some areas are far from live equipment, and while birds may nest or rest there, the impact is minimal. In such cases, rather than going to great lengths to chase them away, it’s better to provide them with a safe place to make their homes.
When building nests, birds prioritize stability and comfort; they might not be willing to live in just any old basket. That’s why Zhenqu Bird Control Technology has launched a series of electric bird deterrent cages in various sizes and shapes.
Bird cages are secured using matching stainless steel clamps or specialized brackets, but they cannot simply be hung in just any location—their installation requires careful consideration. They are primarily mounted on steel towers and utility poles in areas far from insulator strings, conductors, and live joints. For example, crossarms are birds’ favorite perching spots, but the end closest to the conductors is very dangerous. Therefore, we can install the bird cage at the far end of the crossarm, farther away from the conductors, ensuring that birds can live there safely without affecting the power lines.
When it comes to the material used in bird-proof cages, Zhenqu Bird Control Technology’s bird-proof cages are not made of ordinary wire, but rather corrosion-resistant stainless steel. The entire cage is formed from a stainless steel frame using spot welding, with a dense stainless steel mesh welded to the interior, resulting in an extremely sturdy structure. When birds build nests inside, the fine mesh securely holds the nesting materials in place, and the cage will neither deform nor fall apart, thereby solving the problem of “malfunctions caused by falling nesting materials.”
Of course, this doesn’t mean that just because bird-proof cages have been installed, other areas can be neglected. In hazardous areas where birds should definitely not be allowed to approach—such as directly above insulators, near conductor suspension points, and in areas with dense equipment—smart bird deterrents, bird-deterrent baffles, bird-deterrent tags, and bird-proof covers must still be installed as required. This approach is known as “zoning and tailored strategies; prioritizing major risks while allowing minor ones to pass, and scientific allocation.” By establishing defenses in hazardous areas and guiding birds in safe areas, we neither compromise the power grid nor deprive birds of their space! This kind of refined management may well be the best solution for the long-term coexistence of the power grid and birds!
