  • this ribbon cable Since in contrast to a drag chain no relatively moving members are present, this ribbon cable is at least largely free of abrasion, so there are no dusts or the like. This has a positive effect on the lifespan. On the other hand, such a ribbon cable due to greatly reduced abrasion can be used easily in clean and clean rooms. Since the ribbon cables are guided in the common cable sheath, there is no Abrieb between the individual supply lines and the chain links, as is usually the case with a drag chain. In addition, such a ribbon cable compared to a drag chain is comparatively cheap to manufacture and also easy to handle. Finally, this ribbon cable is characterized by a very low noise.
