How do I reduce friction when pulling cable through a conduit?

2025-08-16

Reducing friction is the single most important factor for a successful cable pull, especially in long runs or conduits with multiple bends. The most effective ways to reduce friction are:

  1. Use a Professional Lubricant: A high-quality, water-based, polymer pulling lubricant is essential. It should be applied generously to the cable as it enters the conduit. The lubricant creates a slippery film that drastically reduces the coefficient of friction, lowering the required pulling force and protecting the cable's jacket.

  2. Use Correct Conduit Fill Ratios: As mentioned, maintaining the correct fill ratio prevents the cables from wedging or jamming inside the conduit.

  3. Inspect the Conduit: Before pulling, a thorough inspection of the conduit is necessary. Ensure it is clean of dirt, debris, or sharp edges that could damage the cable or increase friction.

  4. Use Conduit Rollers and Sheaves: For large-diameter cables or in complex runs, using rollers or sheaves at bends and entry points helps guide the cable smoothly and minimizes friction.
