Birds are particularly fond of nesting on power grid towers. These tall, sturdy structures offer expansive views, making them ideal "real estate" for avian inhabitants. However, the issue is that bird activity frequently causes power grid short circuits and tripped circuits, disrupting stable electricity supply. More seriously, the birds themselves may suffer electrocution or collisions with power lines, resulting in injuries or fatalities.
How does the power grid prevent bird-related failures? In addition to installing various bird deterrent devices to keep birds away from hazardous areas of the grid, ecological grid bird guidance systems—essentially artificial birdhouses—are employed to direct birds to suitable locations for nesting and roosting. Non-energized sections of power poles and towers, or crossarm positions distant from insulators and conductors, allow birds to build nests without disrupting grid operations. This approach reduces power outages while accommodating birds' nesting needs, achieving a win-win outcome.
Recently, Kunming Power Supply Bureau installed 500 artificial bird nests in high-risk bird collision zones, near large water sources, and along bird migration routes. These nests provide safer and more comfortable habitats for birds to rest and breed, achieving a win-win outcome for ecological conservation and power grid development.
Shenzhen Zhenquniao Technology's Eco-Grid Bird Attraction Device ZQN-DL-NL is constructed from corrosion-resistant, anti-aging stainless steel, featuring a robust structure and exceptional durability. It comprises five stainless steel frames formed through spot welding, with five additional stainless steel mesh panels welded internally. This design prevents nests from being scattered by strong winds while also avoiding nesting materials falling onto electrical equipment. Additionally, young birds are safer inside and less likely to fall out.
In summary, the overall approach to bird prevention in power grids is gradually shifting toward harmonious coexistence between birds and power lines. Rather than forcibly driving birds away, the focus is on scientifically guiding them to nest in safe locations. This approach ensures the stable operation of the power system while also protecting bird ecosystems.
