Is the cable suitable for moving back and forth TRVV or RVV cable? TRVV cable is composed of copper core, polyvinyl chloride (PVC) insulation, polyvinyl chloride (PVC) sheath, flexible drag chain cable. RVV cable is composed of copper core, polyvinyl chloride (PVC) insulation, polyvinyl chloride (PVC) sheath, flexible wire, which belongs to the 1 type of sheathed wire. From the name of the cable, both cables have soft and soft characteristics, so what is the difference between the two cables: 1. TRVV flexible drag chain cable is mainly suitable for installation and use under continuous reciprocating motion, especially regular high-frequency mobile installation and use under wet or dry industrial environment, such: numerical control airport equipment, automation equipment, modern mechanical standard parts of the drag chain and logistics system, control system, mechanical automation system, mechanical (human) hand, construction machinery, heavy machinery factory, automobile manufacturing, lifting and transportation equipment, automated warehouse, wharf, fire truck and other mechanical equipment and occasions need high frequency mobile bending. In general, cables suitable for moving back and forth shall be TRVV cables. 2. RVV cable shall be used for fixed installation in indoor environment or installation under occasional movement without strong stress release or forced guidance, such as power line, control line and signal transmission line for electrical appliances, instruments and electronic equipment and automation devices, which can be used for anti-theft alarm system, building intercom system, etc. In terms of cable selection, some people's thinking is still on the word "soft 2". They think that as long as the cable feels softer, it can be used as a drag chain cable. Some salespeople also take advantage of this to sell the ordinary cable RVV as a drag chain cable TRVV and use the relatively low price of the ordinary cable to induce customers. In fact, the flexible cable is not necessarily a high flexible cable. High flexibility refers to not softness, but flexibility, refers to the deformation of the object after the force, the force is lost after the object itself can restore the original shape of the 1 physical properties. When choosing a cable that is suitable for moving back and forth, it is not only necessary to have flexibility, but also excellent mechanical strength. Therefore, in the selection of drag chain cable, we can not only rely on the flexibility of the cable to choose, from the equipment trajectory, movement mode and movement environment and other comprehensive measurement.
