What are the two slack methods of stringing wire typically used on?

The two slack methods of stringing wire are primarily utilized for distribution conductors. This technique is designed to facilitate the installation of overhead power lines at lower voltages typically seen in distribution systems. The slack method involves allowing the conductors to hang freely and using tension to maintain proper clearance and alignment, which is essential at lower heights and in more urban or residential environments.

Distribution systems are commonly characterized by their proximity to consumers, making the handling and installation of conductors under slack conditions particularly useful to ensure safety, minimize tension, and allow for thermal expansion or environmental effects. This method is crucial in ensuring that the wire maintains an appropriate sag, ensuring both structural integrity and electrical safety in densely populated areas where distribution lines are more prevalent than transmission lines.

In contrast, transmission conductors, high voltage lines, and substation feeders involve different installation methods due to their specific operational requirements, such as high tension and clearance regulations, which do not typically favor the slack method.
