A tool used to estimate the force exerted on a cable during installation through conduits or raceways is a central component in electrical and telecommunications projects. This estimation considers factors such as cable weight, pulling distance, coefficient of friction between the cable and conduit, and changes in direction (bends). For instance, when installing a large power cable in an underground duct bank with multiple 90-degree bends, accurately predicting the force required to pull the cable prevents damage to the cable’s insulation and conductors.
Accurate force prediction is vital for ensuring the longevity and reliability of cable installations. Underestimated force requirements can lead to cable damage, resulting in costly repairs and service interruptions. Overestimated force requirements can lead to the selection of unnecessarily robust and expensive pulling equipment. Historically, these calculations were performed manually, often leading to inaccuracies. The development of computerized tools has improved accuracy and efficiency, minimizing risks and optimizing resource allocation.
