What are the ways to use wires and cables?

Wires and cables used to transmit power and signals are widely used in various purposes and places. In order to avoid trouble and accidents, it is important to consider the location and purpose when selecting a model.

What are the commonly used packaging methods for wires and cables?

The packaging of cables requires the use of cable drums, which are available in various packaging methods such as iron drums, wooden drums, and iron-framed wooden drums. The way the cable is packaged depends on its type and usage scenario, it can be simple bundling packaging, or more complex reel packaging or artificial flexible packaging. Each type of packaging has its specific advantages and application areas.

1.Bundling packaging

This is one of the common packaging methods for large cables. Steel tape or hemp rope is usually used to bundle the outer layer of the cable, and the bundling points are filled with gaskets to avoid cable damage caused by excessive bundling. This packaging method is low-cost and suitable for short-distance and small-volume transportation, but it may not be strong enough and is susceptible to external impact and extrusion.

2.Wooden pallet packaging

Place the cable on the wooden pallet and fix the cable with surrounding wooden strips or plastic packaging tape. The advantage of wooden pallet packaging is that it has good stability and is suitable for long-distance and large-volume transportation, but it is more expensive, not environmentally friendly enough, and takes up a lot of space.

3.Drum packaging

This is a method of wrapping the cable on a hollow paper tube or plastic drum, which helps to reduce the cross-bending of the cable and has less impact on the mechanical properties of the cable. The reel packaging is easy to handle, facilitates storage and handling, and is less susceptible to damage to worn cable surfaces during transportation. Shaft tray packaging is one of the common packaging methods for overhead bare conductors.

4.Packing in rolls

Wire products can be packed in rolls and fixed with plastic film. Cable products are packaged in wooden trays or steel-wood trays, and the outer trays are covered with a layer of protective film or sealed with wooden boards.

5.Artificial flexible packaging

For certain types of cables, such as rewound wires and cables, artificial flexible packaging is required. This includes choosing the right packing material and height, as well as making sure the cables are wrapped tightly and don't fall apart. Artificial flexible packaging also needs to contain the product’s certificate and test report, which should be packed in a sealed bag and fixed on the cable.

The main methods of using wires and cables are

The use of wire reels

1. The wire coil should be stored in a flat place indoors and should be lifted and carried as much as possible without rolling.
2. The reel cannot be laid flat, otherwise the wire coil wrapped on it will be misaligned and cannot be pulled out.
3. Do not roll the reel. When having to roll a reel, attention must be paid to the direction in which the reel is rolled (roll in a direction where the cable will not unwind). If you turn it in the opposite direction, the cable will come loose and it will be difficult to pull it out.
4. When stacking coils and reels, strict precautions must be taken to prevent them from falling. Excessive shock to wires and cables can cause significant performance degradation. Care must be taken when handling vinyl wire, especially in cold areas, as breakage can easily occur.

Precautions during wiring construction

1. When routing, cobblestones, protrusions, concrete frames and other obstructions must be thoroughly removed. In addition, at the construction site, sufficient attention must be paid to the fact that impacts caused by falling foreign objects and nails on footboards and wooden boxes can easily cause injuries.
2. When wiring the wires wound on the reel, due to repeated changes in tension that cause the wires to change in tension or looseness in the length direction, the wires may pop out or bend near the winding start port. In order to suppress the bending of the electric wire, it is necessary to remove the end of the electric wire when the reel is started and pay attention to the fact that the electric wire protrudes from the winding start port. This is especially important with long, thin cables.
3. When wiring, you need to use rollers, etc. to prevent excessive tension on the wires.
