Due to increasing demands within the field of automation technology in the 1980s, such as increasing loads, moving cables guided inside cable carriers often failed, although the cable carriers themselves did not. In extreme cases, failures caused by “corkscrews” and core ruptures brought entire production lines to a standstill, at high cost. As a result, specialized, highly flexible cables were developed with unique characteristics to differentiate them from standard designs. These are sometimes called “chain-suitable,” “high-flex,” or “continuous flex” cables.
Ultra-Flexible cables for when high performance and high flexibility is required for your application. Designed for high flexure environments, some designs have to be qualified to over 500,000 flexures all will have stranded centre conductors offering more flexible alternative to solid centre conductor cable.
Ultra-flexible cables which provide wideband performance from DC to 18 GHz with low insertion loss and excellent VSWR. The cable is designed for stability of phase and amplitude versus flexure while offering tremendous durability and reliability. Its unique construction of a triple shielded cable with a unique moulded boot allows the cable to have the greatest of flexibility and yet handle the demanding lab environments where constant bending and flexing are required.
Flexible cables can be divided into two types: those with conductors stranded in layers inside the cable, and those that have bundled or braided conductors.
Stranding in layers
Stranding in layers is easier to produce, and therefore usually less expensive. The cable cores are stranded firmly and left relatively long in several layers around the centre and are then enclosed in an extruded tube shaped jacket. In the case of shielded cables, the cores are wrapped up with fleece or foils.
Stranding in bundles
The unique cable construction technique of braiding conductors around a tension-proof centre instead of layering them is the second type of construction.
