Cables-in-drums refer to electrical cables that are wound onto cylindrical spools or drums for storage, transportation, and ease of handling. These drums are designed to protect the cables from damage and environmental factors, ensuring their integrity until they are ready for installation. The use of drums allows for efficient management of long lengths of cable, making it easier to unwind and deploy as needed for various applications, such as construction, telecommunications, and power distribution. Cables-in-drums are commonly used in both industrial and commercial settings, providing a practical solution for cable organization and logistics.
