Accidentally messing with the cable is to prevent cable drag chain, afraid of cable will wear, if put cable to cable drag chain inside not only to have the effect of protection, and can prevent cable a mess is bad to do, and the cable inside the drag chain is also more convenient, if the mobile is can prevent the abrasion of the cable, this structure is called a cable drag chain.
Cable drag chain is made up of several parts, the first is the center of the tensile, each cable no matter how many root core inside, there will be a center line, but the center line of a lot of time is filled with some of the filling material, the material may be not plastic or don't have to wire filling, the filling is can protect the structure of the stranded wire, can prevent the winding ran to the center of the cable.
The second is the structure of the conductor, cable is a good point to choose flexible conductor, special circumstances, the conductor is more thin, so the flexibility of the cable with good, but also not too thin, too thin cable is easily around.
The third is the problem of the insulation, the inside of the cable insulation material is can not be glued together with each other, insulating material is to support single strand of wire, otherwise so many wire guide, it is finished.
The fourth is stranded wire, now because of insulation materials, the structure of the stranded wire should be designed in accordance with the state of motion.Stranded wire is in a mating pitch that around in the center of the stable tensile, but want to be in the center of the tensile around.

The inside of the sheath is made of low price of wool or other filler to fill, like this is to prevent the winding will not spread out.
Outside of the sheath is according to different materials, and have different functions, such as low temperature resistance, high temperature resistance, uv resistance, but they are all have one thing in common, that is not easy to be worn, and won't stick things, out of the sheath is there must be more flexible with supportive, still have to compressive strength.
TRVVSP3 * 2 * 0.3 SQ drag chain cable is suitable for in the workshop, control system used.
TL - 2-15 x cable drag chain have been automated warehouses, nc machine tools, electronic equipment, transportation equipment, such as lifting these places began to widely used.
Enclosed cable drag chain, 25 to 35 is more suitable for use in the workshop.
