/kloc-what is the safe distance for construction under 0/0kV high-voltage line? Are cranes allowed to be hoisted under high-voltage lines, and what is the safe distance?

10KV high-voltage line construction safety distance is 6 meters; 10KV high-voltage line, the safe distance for crane hoisting is ≥ 3m in vertical direction and ≥ 2m in horizontal direction.

What is the safe distance of the high-voltage line?

Electromagnetic radiation intensity exceeds 0.4 microtesla within 220kV high-voltage line100m;

132 kV high-voltage line has an electromagnetic radiation intensity exceeding 0.4 microtesla in the range of tens of meters;

1 1-66 kV high-voltage line with electromagnetic radiation intensity exceeding 0.4 microtesla within a dozen meters;

The electromagnetic radiation intensity of high-voltage lines buried underground only exceeds 0.4 micro Tesla within a few meters.

Regarding the safe distance between high-voltage lines and residential buildings, there is no clear distance regulation in China, but there is a relevant standard that can be converted: the magnetic induction intensity at the location of residential buildings.

The safe distance of high-voltage lines below 1kV is 4m;

1- 10kV high-voltage line has a safe distance of 6m;

The safe distance of 35- 1 10kV high-voltage line is 8m;

154-220kV high-voltage line safety distance is10m;

The safe distance along the 350-500 kV line is15m.

Stay away from residential areas

From the perspective of power safety, and considering the wind deviation caused by strong winds on high-voltage lines, according to Article 5 of the Detailed Rules for the Implementation of the Regulations on the Protection of Power Facilities, "The overhead power line protection zone is a safe area that must be set up to ensure the safe operation of the built overhead power lines and ensure the normal power supply of people's lives. 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:

Under 1kV:1.0m;

1kV- 10kV: 1.5m，

35kV: 3.0m，

66kV- 1 10kV: 4.0m，

154kV-220kV: 5.0m,

330 kV: 6.0 meters

500 kV: 8.5 meters.

The safe distance of high-voltage lines below 1kV is 4m;

1- 10kV high-voltage line has a safe distance of 6m;

The safe distance of 35- 1 10kV high-voltage line is 8m;

154-220kV high-voltage line safety distance is10m;

The safe distance along the 350-500 kV line is15m.
