Ultra Flexible Strands

We specialize in designing rope lay cables, concentric and miniature bunched strands that offer the ultimate in flexibility. These stranded constructions complement our specialty insulated wire products, where flexibility and extended flex-life are primary concerns.

By combining smaller wire gauges into larger conductors, the overall conductor’s geometric resistance to bending and therefore it’s stiffness, is reduced as demonstrated in Fig. 1 comparing the stiffness percentage of several 28 AWG stranding (7/36 is considered to be 100% in this example).

In addition to reducing stiffness, smaller gauge sizes also develop less stress when subjected to bending. As a result conductors with finer stranding will survive a larger number of bending cycles without suffering fatigue in comparison to a conductor manufactured with a coarser single end wire.
