Hello, friend!
Overhead cables are limited in height, with a minimum distance of 6 meters from the ground, but the standards vary in different terrains, such as rural and urban areas, mountains and plains, highways and viaducts.
In the overhead power line protection zone, the horizontal safe distance between the sidelines of voltage conductors at all levels and the building is 40 m when the maximum wind deviation of the conductors is calculated.
The distance between the high voltage line and the residential building should be 20 meters. If the HV line is moved underground, the depth of the HV cable sheath to the ground shall not be less than 0.7m, and under the carriageway and cultivated land shall not be less than 1m.
The distance below 1 kV is 4 m; 1-10KV distance is 6m; 35-110KV distance is 8 m; 154-220KV distance is 10m; 350-500KV distance is 15 m
Thanks!
