Remember that flexible and continuous flex cables are not the same. Flexible control cables may bend during installation but should remain stationary in their final applications. On the other hand, continuous flex cable can move constantly. These cables may also be referred to as chain-suitable cable or high-flex cable. Flex cables have much longer service lives than other types of cable. While typical cables might sustain half a million cycles, these control cables can withstand 1-3 million cycles.
There are two main categories of control cables: control cables stranded in layers and control cables stranded in bundles.
Control cables stranded in layers are easier to make and less expensive than those stranded in bundles. They are designed by laying multiple layers of stranding on top of each other. Because of this construction, the outer layers are pulled and the inner layers are compacted when the cable bends. Eventually, this causes distortion and warping within the flexible cable.
Bundled cables are generally a little more expensive than those stranded in layers. In bundled cables the layers are braided around a tension-proof core. This allows layers to “switch places" throughout the bending, so no one layer is always compressed or always stretched. This gives the control cables a longer lifespan.
Different control cables are designed to meet the needs of different applications. If an application requires twisting, choose torsion cable. For fast data transmission in bus systems, choose bus cable. Consider flexible specialty cables for other challenging flexible cable applications.
