What is the safe distance of a large 80-meter-high high-voltage tower?

The safety distance of a large 80-meter-high high-voltage tower is 8.5 meters according to the specifications, but if the lowest point between the house and the sideline is less than 10 meters, you can complain to the government and ask for demolition.

The 500 kV high-voltage line corridor is 60-75 meters, that is, the width of the high-voltage line corridor refers to the distance between the two sides of the high-voltage line, and no buildings or people can live within the width of the high-voltage line corridor.

In densely populated areas such as factories, mines, towns, market towns, villages, etc. Overhead power line protection zone is an area in two parallel lines formed by the sum of the horizontal distance of the guiding line edge calculated by the maximum wind deviation and the horizontal safe distance from the building. When calculating the maximum wind deflection of voltage conductors at all levels, the horizontal safe distance from the building is as follows:

1.0m below 1 kV

1-10kV1.5m.

35kV 3.0m

66- 1 10 kV 4.0m

154-220kV 5.0m

330 kV 6.0 meters

500 kV 8.5 meters

Two criteria for judging the voltage of high-voltage lines;

1, number of insulators In order to improve the efficiency of long-distance transmission, high voltage and low current transmission are generally used to reduce power loss. The more porcelain bottles, the higher the relative voltage. In China, a voltage higher than 380 volts can be called high voltage. The higher the telephone pole, the higher the voltage. Ordinary cement poles in cities are generally tens of thousands of volts. For high-voltage towers, the number of insulators is 500 kV. 330 kV16; 220 kV 9; 1 10kv 5； But there are usually 1 or more than 2 meetings.

2.500kv transmission lines with split conductors basically use four split conductors, that is, four for one phase, two for 220kv and one for 1 10kv.
