What is the term for sag under ice and wind conditions?

The term for sag under ice and wind conditions is referred to as "maximum sag condition." This terminology captures the greatest amount of sag that a conductor can experience during adverse environmental conditions, such as the accumulation of ice or the force of wind.

Maximum sag is critical for ensuring the safe operation of power lines, as it accounts for the additional weight and stress placed on the cables. Engineers design transmission lines to withstand these maximum sag situations to prevent failures or outages, ensuring that there is adequate clearance under the conductors and that they do not come into contact with each other or nearby objects.

Understanding this concept is vital for anyone involved in the design, maintenance, or installation of overhead electrical systems, as it directly relates to safety and reliability in power distribution during harsh weather events.
