1. Packing

To ensure the quality of power cable transportation, it is necessary to use cable trays for packing cables. Cable trays are categorized based on their materials, including wooden trays, wooden trays with iron frames, and iron trays. Additionally, power cables of different voltages should be packaged and transported using cable trays of appropriate sizes. For cost-effective and efficient transportation, it is recommended that power cables with a voltage class of 10KV or below be packed with cable trays having a disk width of 2.2 meters and a disk diameter of 3.2 meters.

2. Weight

When transporting power cables, attention should be given to the weight of each cable tray. Generally speaking, this weight depends on factors such as the length, specifications, and models of wire and cable being used. Taking low-voltage wire and cable as an example, the length per single disc is typically around 500 meters with a weight ranging from 3 to 10 tons.

3. Transportation

Before transportation begins, it is essential to check whether the wire and cable are tightly wound onto the tray. During transportation itself, laying flat without proper fixation must be strictly avoided, as this increases the risk of damage to the power cables. Given its substantial size, cargo loadage during transportation, if not secured properly, can lead to unimaginable consequences in case they roll off during transit.

4. Head protection

During transportation processes involving wire and cable products, special care must be taken in protecting their heads from moisture or water exposure, which could potentially compromise their integrity or performance capabilities. Any changes observed in head appearance during inspection should prompt immediate action through moisture detection or experimentation procedures aimed at identifying potential damages requiring timely treatment.

5. Unloading

While loading/unloading operations take place for cables, the utmost caution must be taken to avoid damage to the cables and cable trays. Do not push the cable tray directly from the car. Unload the cable carefully.

6. Cable tray storage

The cable tray shall be stored in a centralized storage, and the voltage, model, specification, length, and other information shall be marked in a conspicuous place. The cable tray shall not be stored in a place with water accumulation or dampness. When the cable tray is found to be damaged, it should be replaced immediately to avoid unnecessary losses during the transportation of the power cable.
