Several factors significantly influence the tension experienced by a cable during a pull:

• Cable Weight and Length: The longer and heavier the cable, the greater the gravitational force and friction, leading to higher tension.

• Coefficient of Friction (COF): This is a critical factor determined by the cable's outer jacket material, the conduit material, and the presence of lubrication. Proper lubrication can dramatically reduce the COF, lowering tension and sidewall pressure.

• Number and Angle of Bends: Bends have an exponential multiplying effect on pulling tension. A single 90-degree bend can increase tension more than a long, straight pull. Sidewall pressure, the force exerted on the cable as it goes around a bend, is also a critical factor to monitor.

• Pulling Direction: Choosing the optimal pulling direction, especially in runs with elevation changes or clustered bends, can significantly reduce the overall tension.

• Reel Back Tension: The tension required to unreel the cable from the drum adds to the total pulling force. Our high-quality cable drum stands are designed for smooth rotation to minimize this factor.

• Cable Configuration: When pulling multiple cables, their configuration (e.g., cradled or triangular) can affect the weight correction factor and overall tension.
