2 When packaging in a reel, each cable package should be accompanied by a product quality certificate. The certificate should be placed in an impermeable bag and fixed on the side of the cable reel, indicating:

a. The name or trademark of the manufacturer;

b. Cable model and specifications;

c. Length: m;

d. Date of manufacture: year month;

e. Standard number;

f. Gross weight: kg;

g. Indicates the compliance of the correct rotation direction of the cable reel.

Product transportation and storage

a. The cable should be stored in the open air, and the cable reel is not allowed to be transported or stored flat.

b. The transportation and storage of cables should avoid strong vibration, dumping, moisture, and corrosion. During transportation, loading and unloading, avoid damage to cables and cable reels.

c. Product loading and unloading should be carried out by crane, steam crane or other suitable loading and unloading equipment and tools. During loading and unloading, a steel shaft is inserted into the center hole of the cable reel, and steel ropes are placed on both ends of the shaft for lifting. It is strictly forbidden to directly push down from the transport vehicle or throw down the cable reel with cables from a height.

d. When hoisting packages, it is strictly forbidden to hoist several reels at the same time. On vehicles, ships and other transported parts, the cable reels should be placed stably and fixed with appropriate methods to prevent mutual collision or overturning.
