How can the location of direct buried underground cables be accurately marked and protected?
2025-08-14Answer: Accurate marking and protection of direct buried cables are essential to prevent future damage. The process typically involves:
-
Warning Tape: A brightly colored warning tape, often printed with a clear message like "Danger: High Voltage Cable Below," is laid in the trench at a specific distance above the cable.
-
Cable Markers: Permanent cable markers or posts are installed above ground to indicate the cable route, especially at changes in direction or at the start and end of the run.
-
Utility Mapping: Before and after installation, the cable route is recorded on utility maps, often using GPS coordinates, for future reference.
This multi-layered approach ensures the cable's location is easily identifiable and protected, reducing the risk of accidental damage during future construction or maintenance activities.
