What are the most common challenges in power cable pulling?
2025-08-15The most common challenges in power cable pulling relate to three key factors: friction, tension, and damage.
-
Friction: This is the primary obstacle, caused by bends in the conduit, debris, or the sheer weight of the cable. Excessive friction increases the required pulling force, which can lead to over-tensioning.
-
Tension: Every cable has a maximum allowable pulling tension. Exceeding this limit, even momentarily, can stretch the conductor, damage the insulation, or cause a catastrophic failure.
-
Cable Damage: Damage can occur from over-tensioning, twisting or kinking the cable, or from abrasion against rough surfaces or sharp bends. This is a critical concern as it can lead to premature cable failure and significant project costs.
To overcome these challenges, a planned approach using the right equipment is essential.
