Packaging and Drum:
1. Cable Sheath Marking
Unless otherwise specified, the cable sheath marking shall be as follows:
Color: White
Contents: Brand,the year of manufacture, the type of cable, cable number, length marking
Interval: 1±0.2% m
Outer sheath marking legend can be changed according to user’s requests.
2. Reel Length
Standard reel length: 2/3/4 km/reel, other length is also available.
3. Cable Drum
The cables are packed in plywood wooden drums.
4. Cable Packing
Both ends of the cable will be sealed with suitable plastic caps to prevent the entry of moisture during shipping, handling and storage. The inner end is available for testing.
