What is the small windmill on the wire bar for?

It can repel birds and release static electricity.

the "windmill" installed on the pole has many uses. First of all, this small windmill can release static electricity and avoid lightning strikes. Because the pole is easy to accumulate static electricity in the transmission line, it leads to the accumulation of static charge, which will increase the risk of electric shock. Through the design of small windmill, these static charges can be effectively released and the safety of transmission lines can be protected.

Secondly, this small windmill can also be used to prevent birds from nesting on poles. Many birds like to nest on poles, which may lead to problems such as short circuit of wires and harm to transmission lines. The blades of small windmills can turn with the wind, reflect sunlight and send out flashing signals to drive away birds and prevent them from nesting on poles.

Harm and prevention of bird nesting on telephone poles

Birds nesting on telephone poles may cause harm to power facilities. First of all, birds may grab grass, branches and other things when building nests, and these objects will fall on the wires, which may lead to short circuit or trip of the wires. Secondly, birds may use metal wires, nails and other things when building nests. Once these things touch the wires, they will also lead to short circuit or trip of the wires.

In addition, birds may pick up dirt such as mud when nesting, which will pollute wires and insulation layers, resulting in insulation layer breakage and short circuit.

In order to avoid the harm of telephone pole birds nesting, some measures can be taken. For example, you can install anti-bird stings on telephone poles or use devices such as sound bird repellers to drive away birds. In addition, the poles and wires are inspected regularly, and the bird's nest and dirt are cleaned in time to ensure the normal operation of power facilities.
