What is the safe distance between high-voltage lines and plants?

The power supply line planning of power supply enterprises is fully demonstrated and approved by relevant government departments before implementation. In the process of construction, the relevant national and industrial standards will be strictly observed, and the power supply department will also cut down the newly planted or naturally grown trees and bamboos that may endanger the safety of power facilities in the designated power facilities protection zone to ensure that the safe distance between the lines and plants meets the relevant regulations.

After maximum sag or maximum wind deviation, the safe distance between overhead power line conductors and trees is as follows

The safe distance of 35- 1 10 kV overhead power line conductor at maximum sag is 4.0 meters; The safe distance of maximum wind deviation is 3.5 meters.

154-220kV overhead power line conductor has a safe distance of 4.5m at maximum sag and a safe distance of 4.0m at maximum wind deviation.

The safe distance of 330 kV overhead power line conductor at maximum sag is 5.5 meters; The safe distance of maximum wind deviation is 5.0 meters.

The safety distance of 500 kV overhead power line conductor at maximum sag is 7.0 meters; The safe distance of maximum wind deviation is 7.0 meters.

1- 10 kV overhead power line conductor's safe distance at maximum sag is 1.5(0.8) meters; The safe distance of maximum wind deviation is 2.0( 1.0) meters.

The safe distance of overhead power line conductors below 1 kV at maximum sag is 1.0(0.2) m; The safe distance of maximum wind deviation is 1.0(0.5) meters.
