In a previous article, we explored how Cable in Conduit (CIC) can help simplify installations by combining cable and conduit into a single factory-assembled system. However, traditional cable pulling still remains the most common installation method used across the industry today. Understanding the benefits, challenges, and planning considerations associated with cable pulling can help contractors select the best installation approach for their next project.

Cable pulling is often performed when installing large feeder cables through long or complex routing paths. Using pull ropes and mechanical tuggers, cables can be installed through conduit systems, cable trays, ducts, trenches, and other designated pathways. This practice is preferred by many installers because of its flexibility, efficiency, and ability to accommodate a wide range of cable types in various installation environments.

Despite its prevalence in the industry, cable pulling can present several technical challenges that can impact installation quality and long-term system reliability. Excessive pulling tension, inadequate lubrication, improper bend radii, or poor handling practices can damage the cable, compromise the conductors, or create small defects that may not become apparent until after the system is energized. These risks are often amplified on large projects where cables must navigate multiple bends, vertical risers, or extended underground conduit systems. To help mitigate these issues, installers frequently use cable rollers and corner sheaves along the cable route. Rollers can reduce friction by supporting the cable and preventing it from dragging across rough or sharp surfaces, while properly sized corner sheaves distribute forces around bends and help minimize sidewall pressure.
