Technical Principles Of Flexible Cables

From a technical standpoint, the exceptional flexibility of flexible cables stems primarily from their specialized structural design. Typically, the conductors are composed of multiple strands of fine copper or aluminum wire twisted together; this configuration not only enhances electrical conductivity but also significantly improves the cable's ability to withstand bending and twisting. Furthermore, the insulation and sheath layers are made from flexible, wear-resistant materials-such as rubber, polyvinyl chloride (PVC), or polyurethane (PU)-which offer excellent electrical insulation properties while effectively resisting environmental degradation and abrasion.
