• 1. Packaging Materials:

• Cable Reels: The cable is usually wound on sturdy steel cable reels. The steel cable reels are made of high-quality carbon steel, with a thickness of 5-8mm, which has strong load-bearing capacity and impact resistance. The diameter of the cable reel is determined according to the length of the cable, generally 1200mm, 1500mm, or 1800mm, to ensure that the cable can be neatly wound without excessive bending. The two sides of the cable reel are equipped with flange plates with a height of 300-500mm, which can effectively prevent the cable from slipping during transportation.

• Protective Layers: The outer layer of the cable is first wrapped with a layer of moisture-proof plastic film, which is made of high-density polyethylene (HDPE) material with a thickness of 0.1-0.15mm, having good moisture resistance and tensile strength to prevent the cable from getting damp. Then, a layer of non-woven fabric is wrapped outside the plastic film to avoid direct friction between the plastic film and the cable reel, reducing the risk of damage to the plastic film. For long-distance transportation or export products, an additional layer of galvanized iron sheet is wrapped around the cable reel to enhance the overall protection, preventing the cable from being damaged by external impacts and harsh weather conditions.

• 2. Packaging Methods:

• Winding: When winding the cable onto the reel, control the winding tension uniformly to ensure that the cable is tightly and neatly arranged on the reel without overlapping or loosening. The winding speed is set to 5-10m/min to avoid excessive tension that may damage the cable structure.

• Fixing: After winding, use steel straps with a width of 25mm and a thickness of 0.8mm to fix the cable on the reel. The steel straps are tightened at intervals of 300-500mm along the axial direction of the reel to ensure that the cable does not move during transportation. In addition, the end of the cable is fixed with a special cable clamp to prevent the cable head from loosening and being damaged.
