The so-called leaky cable, the leaky induction cable, is an outdoor perimeter intrusion detection system, mainly used in banks, vaults, high-end residential buildings, prisons, warehouses, museums, power stations (including nuclear power plants), military agencies and facilities, bases, oil fields, cultural relics. Protection and other alarms that require outdoor perimeter protection can also be used as indoor protective alarms. In order to ensure the normal use of leaky cables, there are certain precautions in the installation process. What should be paid attention to when installing leaky cables? What? Look at the following points and you will know. 1. The two cables must be laid in parallel, with a spacing of 1-3 meters and an optimum spacing of 1.5 meters. 2. The two cables should not cross each other and be installed close to each other. The excess cable should be cut off; 3. The cable placement attempt is determined according to the medium. Under normal circumstances, the buried depth of the mud is 10-20 cm, and the depth of the cement is 3-7 cm; 4. The plane drop when the two cables are laid in parallel is not less than 135 degrees; 5. When installing two sets of cables, ensure that there are overlap zones of about 3 meters between the adjacent two sets of leaking cables, and that the two sets of cables should have a spacing of about 0.3 meters in the overlap zone, and the adjacent sets of leaks. The operating frequency of the host of the cable should be staggered; 6. When the host is installed outdoors, it is necessary to add a waterproof protection box to the host; 7. The power cable and signal cable cannot be installed close to the leaking cable. The distance between the signal cable and the leakage power charge should be greater than 30 cm. The distance between the 220V power cable and the leaking cable should be 1 meter away. 8. The standard length of the non-leakage cable connecting the host to the leaky cable is 10 meters. The two non-leakage cables should be protected by pipes, which can be PVC pipes or steel pipes. The distance between the two non-leakage is more than 10 cm; 9. The buried cable should be placed at a distance of more than 2 meters from the sidewalk and more than 4 meters from the road; 10. Two leaking cables should be placed in a 32MM PVC pipe and buried in the ground. Do not penetrate into the steel pipe; 11. If the leaking cable is buried on one side of the wall, it needs to be 1 meter away from the wall. Under normal circumstances, the installation of the leaky cable is a professional construction knowledge, but we can also carry out cable installation quality inspection according to the above installation precautions to ensure that it can be used normally.
