Underground Cabling Solution for Electric Utilities

This document is a case study detailing the implementation of an underground cabling solution designed by Southwire's CableTechSupport™ Services team for one of the largest electric utility companies in the U.S. The project aimed to replace overhead power lines in a residential area with a new underground system to mitigate power outages caused by falling trees and vegetation. The solution involved the use of 600-volt rated USE-2 cables installed via Horizontal Directional Drilling (HDD), which minimized disruption and environmental impact. The project resulted in significant cost savings, approximately $50,000, through reduced labor and material expenses. The case study outlines the challenges of conventional trenching methods and highlights the advantages of the all-in-one Cable-in-Conduit (CIC) assemblies, which can be installed efficiently across various soil conditions. Additionally, it mentions the mission of Southwire's Re3™ Consultation Services, which focuses on responding to user challenges, rectifying issues, and restoring electrical systems.
