A cable pulling tension calculator is a tool or software used to estimate the maximum force required to pull a cable through a conduit or duct run. This calculation is critically important for preventing damage to the cable during installation. The maximum allowable pulling tension is determined by the cable's construction and is specified by the manufacturer. Exceeding this tension can lead to sheath fracture, conductor deformation, and insulation damage, which can cause premature failure.

Calculating tension is important because it helps to:

• Prevent Cable Damage: Ensures that the pulling force remains below the manufacturer's specified limit.

• Select the Right Equipment: Determines the capacity needed for the cable winch and other pulling tools.

• Optimize the Pulling Path: Helps identify potential problem areas in the cable run, such as tight bends or long sections, where tension could become excessive.

• Ensure Safety: Reduces the risk of equipment failure or a sudden snap of the pulling rope, which could endanger workers.
