What is The Trailing and Reeling Cable and Its Types?
Znergy CableThe heavy-duty and rugged electrical cables used for industry, like construction, mining, and material handling, are the need of the day. Industrial environment cables may have to face repeated bending, heavy mechanical stress, tough environmental conditions, and repeated flexing. That is where reeling and trailing cables come into play. They are equipped with the ability to resist hard conditions, providing safe power to heavy machines and mobile machinery.

This blog describes what trailing and reeling cables are, where they are used, and what they are, specifically Type 275 Cable, Type 406 Cable, 241.1 Trailing Cable, Type 409 Cable, Type 450 Cable, Type 241.1 Cables, Type 441 Cables, and Type 2S Cable.
What are Trailing and Reeling Cables?
Trailing cables are robust, flexible power cables used for powering huge mobile or portable equipment like draglines, drills, shovels, stackers, reclaimers, and conveyors. They "trail" along the ground as the machines move themselves from location to location, and they withstand harsh handling, tension, torsion, and abrasion. They are made with reinforced sheaths and insulation so that they can withstand oil, water, chemical contact, and physical abuse.
Reeling cables are employed in those applications where the cable needs to be reeled and unwound several times over a drum, i.e., in hoists, material handling devices, and cranes. Use cables of such application need to resist bending stresses and torsional loads during unwinding and winding.
Trailing and reeling cables play an important role in avoiding no power and control signal discontinuity in dynamic industrial situations.
