What is the purpose of sealing cable ends that are in storage?

Sealing cable ends that are in storage is primarily intended to keep moisture from entering. Moisture can lead to corrosion and deterioration of the cable's conductive materials, which can significantly impair its performance and longevity. By sealing the ends, you create a barrier that helps maintain the integrity of the cables, ensuring they remain dry and functional when needed.

Other options, while they may have some relevance, do not address the main concern associated with storing cables. For instance, preventing theft is not typically a reason for sealing ends, as other security measures would be more effective for that purpose. Identifying the cable type can be important but is generally done through labeling rather than sealing. Regulating temperature, while a consideration in some storage scenarios, is not directly related to the sealing of cable ends. Therefore, sealing primarily serves to protect the cables from moisture exposure.
