Leakage cable installation

1. Two cables should not cross or be installed close to each other, and excess cables should be cut off; (including non leaking cables);

2. Two cables must be laid parallel, with a spacing of 1-3 meters and a spacing of 1.5 meters;

3. The placement of cables is determined based on the medium. Generally, the burial depth of mud soil is 10-20 centimeters, and that of cement soil is 3-7 centimeters;

4. The plane drop when two cables are laid in parallel shall not be less than 135 degrees;

5. When installing two sets of cables, it should be ensured that there is an overlap area of about 3 meters between the adjacent leaked cable tails, and a gap of about 0.3 meters should be maintained between the two sets of cables in the overlap area. The working frequency of the host of two adjacent sets of leaked cables should be staggered;

6. When the host is installed outdoors, a waterproof protection box should be added to the host;

7. The power and signal lines should not be installed parallel to the leaking cable. The distance between the signal line and the leaking electricity bill should be greater than 30 centimeters, and the distance between the 220V power line and the leaking cable should be more than 1 meter;

8. The standard length of the non leaking cable connecting the host and the leaking cable is 10 meters. The two non leaking cables should be protected through separate pipes, which can be PVC pipes or steel pipes. The distance between two non leaks is more than 10 centimeters;

9. Two leaking cables should be installed in a 32MM PVC pipe and then buried underground, and cannot be penetrated into steel pipes;

10. The buried location of leaked cables should be at least 2 meters away from the sidewalk and at least 4 meters away from the highway;

11. If the leaking cable is buried on one side of the wall, it needs to be 1 meter away from the wall.
