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

In aerial installations, the standard practice is to allow for sufficient slack cable to accommodate various factors such as tension, environmental conditions, and the possibility of future maintenance or adjustments. Typically, 15 to 25 meters of slack cable is used because this range provides a good balance between having enough cable for flexibility without excessive lengths that could cause management issues or unnecessary waste. This allowance helps in ensuring the integrity and reliability of the installation over time, as cable can be subjected to movement or tightening, particularly in outdoor environments where conditions can change. Thus, 15 to 25 meters is considered an optimal standard for maintaining functionality and serviceability in aerial installations.
