What is a tugger used for in cable installation?

A tugger is a specialized device used in cable installation primarily to assist in advancing cables within a conduit. Its function is to facilitate the smooth and efficient pulling of cables, reducing the friction and potential damage that can occur when cables are manually pushed or pulled through tight spaces or long lengths of conduit.

When dealing with heavy or numerous cables, a tugger becomes especially valuable, as it helps ensure that the cable installation process is both quicker and safer. This is crucial in preventing physical strain on workers and minimizing the risk of cable damage.

The other options refer to different tools or methods in the cable installation process. For instance, labeling cables for identification is carried out with labeling tools and markers rather than a tugger. Measuring the pulling force involves different instruments that track force and tension rather than the function of a tugger. Additionally, splicing cables requires specific splicing tools and techniques, not the capabilities of a tugger. Therefore, the use of a tugger is distinctly focused on advancing cables, making this answer the most appropriate in the context of cable installation.
