What are the primary phases of an underground cable installation project?
2025-08-16A professional underground cable installation project is a systematic process with distinct phases. We categorize the process into three main stages:
-
Preparation Phase: This involves all the work done before a single foot of cable is laid. It includes a thorough site survey and route planning, which is essential for identifying all existing underground utilities. This phase also includes securing all necessary permits and preparing the site by digging trenches or initiating horizontal directional drilling. The right tools for this phase ensure the cable path is clear and safe.
-
Installation Phase: This is the core on-site work. It involves the use of specialized equipment to safely and efficiently pull the cable through trenches or conduits. This includes setting up hydraulic drum stands to unspool the cable, using a duct rodder to feed a pulling rope, and operating a hydraulic cable puller to apply the precise, controlled tension needed to move the cable without damage.
-
Restoration and Commissioning Phase: Once the cable is successfully installed, the trench is backfilled and compacted to prevent future ground settling. Warning tape is often placed as a final safety measure. Before the system goes live, thorough testing and commissioning are performed to verify the integrity of the insulation and ensure the entire system is ready to carry its electrical load.
