Cables are extremely heavy: Large cables, especially high-voltage and ultra-high-voltage power cables or submarine cables, are often extremely heavy. A single cable reel can weigh tens or even hundreds of tons. The wooden reel must possess extremely high structural strength to support this weight and prevent deformation or collapse during transportation, lifting, and storage, which could damage or crush the cables within.
Resisting Bending Stress:
When the cable is wound around the reel, the innermost cables experience the greatest bending stress. The wooden reel provides a strong, smooth curved surface, ensuring that the cable's bend radius is always greater than its minimum allowable bend radius. Excessively small bend radiuses can cause irreversible damage to the cable's insulation, shielding, and conductors, seriously impacting its electrical performance and lifespan.
Standardized Lifting and Transportation:
The steel (or wooden) side panels at both ends of the wooden reel are designed with forklift and lifting holes, allowing the heavy cable reel to be easily loaded, unloaded, moved, and secured using standard logistics equipment such as forklifts and cranes.
Easy to Roll:
On construction sites, cable drums sometimes need to be moved short distances. The round wooden shaft allows for easy rolling, significantly saving manpower and time.
Orderly Retraction and Retraction, Avoiding Tangling:
Thousands of meters of cable neatly wound on wooden shafts ensure smooth and orderly payout during installation, significantly preventing tangles, knots, and twists. This is crucial for delicate cables such as fiber-optic composite cables.
Protecting Structural Integrity:
Winding flat cables, armored cables, or cables with specific orientations on shafts helps maintain their factory-provided structural form.
Cost-Effective:
Compared to all-steel reels, wooden shafts (typically a hybrid steel-wood structure with a steel center and a wooden surface) meet strength requirements while offering lower manufacturing costs and reduced weight.
Customizable and Environmentally Friendly:
Wooden shafts can be flexibly customized to accommodate cables of varying lengths and diameters. In addition, high-quality wooden shafts can be reused many times and are easy to repair if damaged, and wood itself is a renewable resource.
