Flexible cables for the e-chain®: an overview of chainflex® cables

If they are to have a long service life, flexible cables used in energy chains or robots must have special properties. Our cables have been optimised for a wide variety of applications. The igus chainflex product range includes everything from control cables, servo cables, motor cables, and robot cables to bus cables, data cables, encoder cables and fibre optic cables.

Cable for linear energy chains

Using a cable in an energy chain subjects it to movement and torsion, resulting in high loads. Our expertise in this  area is based on our experience from countless tests performed over the course of 30 years. Cable loading is greatly dependent on travel and bend radius. We have developed seven rules to counteract this loading. They enable us to achieve especially high cable quality and offer the right cable for various requirements such as gusset-filling extrusion or special core stranding.

Robot cable

Robot cables are often also called torsion cables. This clearly indicates the completely different type of movement that it is designed to facilitate. In this field of application, we have also gathered a number of insights in our laboratory over the last few years. Two of the most import are a different shielding concept and a soft design that absorbs movement within the cable. Over the course of countless tests, we have developed a clear definition of durability in terms of movement, since there is no normative reference. Our definition clearly states that a cable is considered a robot cable only if it has a guaranteed service life of five million cycles at +/- 180 degrees/m.
