How tall are 110KV high-voltage utility poles generally?
Thread Content
When planning the layout of the factory site, there is a planned 110KV high-voltage line outside the production area, but it’s not possible to determine its height. How tall is a high-voltage pole like this?

The required height above the ground for 1–10 kV lines is 6.5 meters or more when passing through residential areas, and 5.5 meters or more in non-residential areas. 35-110 kV lines: not less than 7 to 7.5 meters when passing through residential areas, and not less than 6 meters in non-residential areas. 220 kV lines: at least 8.5 meters away from residential areas, and at least 6.5 meters away from non-residential areas. 500 kV lines: at least 14 meters away from residential areas, and at least 7.5 meters away from non-residential areas. Horizontal safety distance: The horizontal distance at which the outer edge of the conductor extends outward increases as the voltage level rises; it is 5 meters for 1–10 kV, and up to 20 meters for 500 kV. Special areas: In areas with difficult access or under conditions of maximum calculated sag, it is necessary to ensure that a statutory safe clearance exists between the conductors and buildings as well as the ground, in order to prevent the risk of discharge.
