Birds are the most direct reflection of ecological conditions. As environmental protection efforts intensify, an increasing number of birds have been appearing around us—a beautiful picture of harmonious coexistence between humans and nature. However, in specific settings such as power infrastructure and agricultural production, bird presence and nesting pose significant safety hazards and economic losses that cannot be ignored.
On transmission lines, debris such as wires and dry grass carried by crows and magpies can easily trigger flashovers on insulators or cause short circuits and tripping during rainy weather. Bird droppings contain acidic substances that accelerate equipment corrosion and degrade insulation performance. According to statistics from State Grid's relevant departments, incidents caused by bird-related faults—such as short circuits and circuit breakers tripping—are rising year by year. The direct and indirect economic losses caused by bird damage at substations are substantial. In orchards, birds pecking at fruit lead to reduced yields, causing great distress among farmers.
To address this challenge, Hizhuo Technology offers a highly effective and eco-friendly solution with its ultrasonic bird deterrent devices. Its flagship product, the HIZ-SP-NSB ultrasonic bird repeller, leverages birds' extreme sensitivity to high-frequency sound waves. It emits ultrasonic frequencies (ranging from 16 kHz to 25 kHz) inaudible to humans, precisely stimulating birds’ auditory and nervous systems. This stimulation induces discomfort and agitation, discouraging birds from lingering, nesting, or foraging within the coverage area.
In terms of power supply, Hizhuo’s ultrasonic bird repellents primarily use solar energy, eliminating the need for external power sources or exposed wiring. This design is especially suitable for remote locations such as outdoor transmission towers and isolated substations where electricity access is unavailable. Simply mounting the solar panel upward on the cross-beam of a tower’s steel structure allows one maintenance worker to install a unit in just ten minutes. Even during prolonged periods of overcast or rainy weather, the built-in energy storage system ensures continuous operation.
Beyond core applications in power transmission lines, substations, and outdoor switchgear areas, these ultrasonic bird repellents are also ideal for orchards, fish ponds, farmland, warehouses, and other sites. Guided by the core philosophy of “technology-based bird deterrence + ecological conservation,” Hizhuo Technology has found a balanced solution using science and technology—ensuring both operational safety and ecological harmony. Let birds return to nature, let equipment stay safe, and let harvests remain untouched.
