What are the different methods for laying underground cables, and which one is the most reliable?
2025-08-14
A1: The most common methods for laying underground cables are:
-
Direct Laying: The cable is buried directly in a trench. This method is economical but has the lowest protection against mechanical damage.
-
Draw-in System: Cables are pulled through ducts or conduits. This provides excellent protection and allows for future replacement or expansion without re-excavation.
-
Troughing System: The cables are placed in pre-cast concrete or fiberglass troughs, which are then covered. This method offers good protection and is ideal for situations where multiple cables need to be routed together.
The draw-in system is generally considered the most reliable due to its superior protection and ease of maintenance, despite a higher initial cost. For all these methods, we offer a comprehensive range of equipment, including trenchers, underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers, and pulling winches, to ensure a safe and efficient installation.
