"After installing the ultrasonic animal repelling device, birds, squirrels, and other small animals will stay away from power lines. In this way, not only will the line failure rates be reduced, but also the lives of small animals will be guaranteed ,"said Huang Wei, a staff member at Baihe Power Supply Station of State Grid TiantaiTaizhou Power Supply Company.

During the National Day holiday, staff members there continue to install ultrasonic animal repellent devices on 10-kilovolt lines.

As small animals often touch the equipment on the electric poles, it is easy to cause phase-to-phase short circuits of the lines. Faulty electric poles are generally located at the junction of urban and rural areas or in remote areas.

The electric poles and the equipment on the poles have a stable structure and are in a warm state for a long time, and can easily become a "resort" for small animals around to inhabit. Small animals such as birds and squirrels like to move on towers. Especially in spring and summer, the climate is often cloudy and humid.

The iron wires, firewood and daily excrement brought by birds during nest building will be blown off by the wind in some cases, which will cause insulator flashovers or short-circuit accidents. In this case, it often harms the safe operation of the power grid.

After careful exploration and discussion, the staff of State Grid Taizhou Power Supply Company decided to install ultrasonic animal repellent devices. In this way, overhead lines can better resist the interference of external factors such as bad weather and branch touch.

They will greatly reduce the probability of failures and ensure the continuous and stable electricity transmission. This is not only of great significance for local industrial production and residents' lives but also will provide a solid power backing for regional economic development.

This measure further improves the operation stability and safety of overhead lines. State Grid Taizhou Power Supply Company staff installed ultrasonic animal repellent devices at pole positions with potential safety hazards on the same day. These ultrasonic animal repellent devices have the characteristics of high intelligence and precision, and can effectively deal with various complex environments and emergencies.

The effective detection and repelling of small animals can make small animals consciously fly away from the "forbidden area" without being harmed, which not only ensures the safety of the power grid but also maintains ecological harmony, and solves the hidden dangers caused by small animals climbing poles to the stable operation of lines.

This innovative measure marks another important step State Grid Taizhou Power Supply Company took in power facility construction and management.

It is believed that with the application of more advanced technologies and equipment, the operation of overhead lines will soon be safer, stable and reliable.
