For engineers and technicians seeking maximum performance and reliability in critical systems.

The integrity of a cable system for mobile applications, whether in overhead cranes, festoons, or cable carrier systems, is defined not only by the intrinsic quality of the cable, but fundamentally by the procedures adopted in its handling and storage. Neglecting these preliminary steps is one of the main causes of premature failures, resulting in unscheduled downtime, high maintenance costs, and operational risks. This in-depth guide is intended for engineers and technicians, detailing best practices with technical justification to ensure maximum service life and performance of Innovcable cables.

Coil Handling: The Engineering Behind Correct Movement

Improper handling of reels is a primary vector for the introduction of latent defects that will manifest themselves during operation. The correct approach goes beyond simple transport; it's about preserving the structural and electrical integrity of the cable.

Fundamental Principles for Transportation and Handling:

• Prohibition of Rolling on the Flanges: The practice of rolling reels on their flanges, although common, is extremely harmful. This action concentrates the load on specific points, which can lead to bending of the flange and, consequently, uncontrolled compression of the cable. The recommended method is the use of appropriate equipment, such as forklifts with forks long enough to support both flanges simultaneously or cranes with axles passing through the reel's eyelet. This approach distributes the force evenly, preserving both the reel and the cable.
• Controlled Movement and the Prevention of Torsional Stress: If rolling is unavoidable over short distances, the execution must be precise. Roll the spool in the opposite direction to the winding of the cable. This technique, counterintuitive to many, is crucial. By winding in the opposite direction, the natural tension of the cable on the reel is maintained, preventing the coils from loosening. Loose coils are susceptible to bends, knots, and, more critically, the introduction of residual twist. This torsional stress, when uncontrolled, can lead to the phenomenon of "champagne cork" or... corkscrewing during installation, irreversibly damaging the internal structure of the cable.
• Team Qualification: Performing these procedures requires trained personnel who are aware of the physical implications of each movement. Mitigating failures begins with the technical training of the team responsible for receiving and handling materials.

Strategic Storage: Mitigating Environmental and Mechanical Degradation

The location and method of storage are crucial for preserving the properties of the materials that make up the cable. Exposure to unsuitable environments can accelerate degradation processes, compromising performance and safety.

Essential Guidelines for Packaging:

• Maintenance on the Original Coil: The cables should remain on their original factory reels until the time of installation. This practice ensures that the cable is packaged with the correct winding tension and protected by the reel structure, preventing the formation of bends, creases, or exceeding the minimum bending radius.
• Strict Environmental Control: Storage should be carried out in a covered, dry place with controlled temperature. Direct exposure to ultraviolet (UV) radiation from the sun triggers a photo-oxidation process in the polymers of the outer coating (sheath), breaking the polymer chains and resulting in drying, cracking, and loss of dielectric and mechanical properties. Cables such as the line Movflex by InnovcableProducts that utilize high-performance compounds such as PUR (Polyurethane) with UV protection already possess superior resistance, but good storage practices amplify this durability.
• End Sealing – The Barrier Against Moisture: Moisture is detrimental to cable integrity. Water infiltration through capillary action can oxidize copper conductors and compromise insulation resistance. It is imperative that cable ends be hermetically sealed, preferably with heat-shrinkable sealing caps. This measure creates an effective barrier against the entry of moisture and other contaminants during storage.

Pre-Operational Verification: The Final Risk Mitigation Step

Before commissioning and full operation, it is crucial to perform functional tests on the entire system.

• Operational Cycle Simulation: Perform multiple operating cycles of the equipment (winding, unwinding, lateral movement) at controlled speed. This step allows for the natural settling of the cable within the system and the identification of any stress points, excessive friction, or mechanical misalignment that may have gone unnoticed during installation. Careful observation of the cable's behavior at this stage is crucial for detecting potential faults before they cause significant damage.

Strict adherence to these technical procedures is not just a recommendation, but a direct investment in the reliability and longevity of your system. By treating handling and storage with the same seriousness you dedicate to cable specifications, you ensure that the performance designed by Innovcable engineering is effectively delivered in your operation.
