How to Pay Attention to Details in the Shipping Process of Cable Reels
We are aware that there may be some issues during the shipping process of the wire spools, which can lead to quality inconsistencies at certain times. These situations, particularly during transportation, require our attention to prevent such issues from occurring.
Cable drums must not be transported lying flat, as this can cause the cables to unwind and easily damage the drum. Power cables are typically wound on drum reels for transportation, storage, and installation. Short cables of less than 30 meters can also be coiled into a circle with a radius not less than the cable's allowed minimum bend radius, and should be tied securely at least four times before handling. In the past, cable drums for mining cables were mostly wooden, but now they are predominantly made of steel due to their durability and resistance to damage, which is beneficial for cable protection. Moreover, these steel drums are reusable, making them more economical than wooden drums. During transportation, it is crucial to protect the cables and ensure that they do not encounter issues due to these reasons.
During the transportation and handling of cable drums, the key issue is to avoid any damage to the cables and to prevent the insulation from being compromised. Although this is a well-known issue, it still occurs frequently, thus it warrants sufficient attention.
Cable drums are typically transported using cranes. When being transported on a vehicle, the foot massage sand should be securely and stably placed, and the edges of the cable drum should be properly padded to prevent the drum from rocking, colliding with each other, or tipping over. A thorough inspection is mandatory before transporting the cables, ensuring they are in perfect condition and the cable ends are sealed tightly. The inner and outer ends of the cables, as well as the oil pipes between the oil-filled cables and the pressure box, must be securely fastened on the drum to avoid loosening due to vibrations during transportation. The oil supply valves on the pressure box should be open, with normal pressure readings; the exterior of the cable should be properly protected to prevent damage from foreign objects. Any issues should be addressed before loading the vehicle for transport.
