Birds really go to great lengths to build nests on power towers and substations—some carry twigs, others bring wire, and some even pick up shiny aluminum wires from construction sites. These items are treasures in their beaks, but once they fall onto our live insulator strings, they become potential hazards that could trigger a fault at any moment, forcing maintenance crews to get up in the middle of the night to make emergency repairs.
Even more of a headache is bird droppings, which are both conductive and corrosive. If they accumulate over a large area on insulators, they can easily cause contamination flashovers or line flashovers and tripping during rainy or foggy weather. In the past, power grid operators struggled with this issue constantly, but things have finally improved somewhat since the installation of these bird-dropping-proof umbrella-style insulator shields (hereinafter referred to as: bird-proof shields).
At first glance, the bird-proof shield looks like a large straw hat placed over a string of insulators. Its primary function is to “block.” No matter how much the birds above flutter about—whether it’s falling branches, pieces of wire, or bird droppings—this shield will catch it all securely. With it in place, the insulators below remain remarkably clean. As long as the insulators stay clean, the risk of flashover and short circuits is reduced by more than half.
In terms of materials, the bird-proof baffle is made of high-strength epoxy resin insulation material, which is heat-resistant, weather-resistant, and wear-resistant. Even after being exposed to the elements outdoors for several years, it will still maintain excellent insulation properties and won’t fail easily.
As for installation, some bird deterrents in the past were tied with wire, and they would sway back and forth in the wind—they looked downright precarious. Zhenqu Bird Control Technology’s bird deterrent panels come with specialized L-shaped brackets that are directly secured to the angle iron of the steel tower. Once the bolts are tightened, they’re incredibly stable—no matter how strong the wind blows, they won’t budge. The installation process is also quick; a skilled technician can install one in just a few minutes, significantly reducing the time required for work at heights.
In the long run, bird-proof barriers don’t drive birds away—they “divert” them. By using the simplest form of physical separation, they not only ensure the reliability of our power supply but also give the birds a way to survive. This harmonious design approach for power lines is exactly what our modern power grid should look like!
