How many meters of slack cable are typically used in aerial installation?

In aerial installations, the typical amount of slack cable used is crucial for accommodating various factors such as tension, temperature changes, and potential expansion or contraction of the cable. Selecting 15-25 meters as the standard range for slack cable is appropriate due to several reasons.

This range allows for a sufficient buffer to handle installation adjustments and protect the cables from stress during climate fluctuations. Furthermore, having this amount of slack can also facilitate maintenance activities and future upgrades without the need for major rework. It ensures that the cable remains functional and safe even when subjected to environmental changes or when additional equipment is added in the future.

Using less than 15 meters might not provide enough flexibility or safety margin, while opting for more than 25 meters may lead to unnecessary cable management issues and increased costs. Therefore, the range of 15-25 meters strikes a balance that promotes effective installation while also considering practical aspects of cable management and environmental factors.
