Installation of cables and equipment is an important step in the use process, both for safety and performance... Drum cable as a widely used cable, of course, its correct installation method is also worth knowing, the following are common drum cable installation precautions:

One: selection of drum cable
The technical difficulty of cable drum is to ensure the synchronization of winding speed and equipment moving speed, and at the same time to ensure that the cable is not damaged in the process of winding, to achieve the purpose of long-term stable use. Therefore, it is required that the following factors should be considered in the selection of drum cable.
1. Cable bearing capacity N: cable type, winding length, drum installation method, equipment moving speed, and is elastic or hammer drum is closely related.
2. Installation environment: outdoor or indoor, whether salt alkali alkali, corrosion, whether it will be subject to external inevitable hard force before.
3. Bending radius of the drum cable: The minimum bending radius of the cable must be smaller than the drum radius.
4. The cable diameter (thickness) matches the drum groove width: the cable diameter is too large and the inner groove width of the drum is too narrow: The cable can not enter the drum groove, cable and cable, cable and drum groove convex part is easy to be severely squeezed, serious cable wear, especially in the case of long stroke, cable moving up and down to bear large tension, more prone to jacket wear, cable winding, broken core.
The cable diameter is too small and the groove inside the drum is too wide: the cable jumps out of the cable groove, resulting in two cables squeezed in one cable groove, and the cable and the drum groove contact area is small, easy to twist itself. The cable will also appear compression, wear, spin, small core is extruded and pulled off.
5. The cable length should match the moving distance of the equipment: too long: the horizontal moving cable is easy to drag wear, the end of the cable is easy to sag and shake when moving up and down, the fixed end of the cable is easy to break or wear at the bayonet, and increase the risk of cable bump; Long too short: the cable bears large tension for a long time, increases the friction with the reel, the sheath is easy to deform, and the small wire core is easy to be broken.
If the selection is not correct, it is easy to produce cable spin, twist; Broken core, jacket wear and other problems.
Two: drum cable installation
1. The cable should be in free state to prevent torsion and rotation of the cable. (The cable must be wound on the equipment drum without twist)
2. Cables must be installed according to the correct operation specifications.
