The installation is a systematic process that requires specialized equipment to ensure the cables are not damaged.

1. Surveying and Trenching: The installation begins with a thorough site survey to identify existing utilities. A trench is then excavated to a specific depth, which varies based on local codes and the cable's voltage.

2. Laying the Conduit and Cable: Conduits are laid in the trench. A pulling line is fed through the conduit using a duct rodder. The cable is then attached to the pulling line with a wire mesh grip and pulled through the conduit using a hydraulic cable puller. This ensures a smooth, controlled installation.

3. Jointing and Termination: After the cable is in place, skilled technicians perform splicing and termination, connecting the cable sections and linking them to the electrical grid.

4. Backfilling and Restoration: The trench is carefully backfilled with a protective layer (often sand) and then the excavated soil, which is compacted in layers to prevent settling.
